+    Apache Lucene OpenNLP integration module
+  </title>
+</head>
+<body>
+<p>
+  This module exposes functionality from
+  <a href="http://opennlp.apache.org">Apache OpenNLP</a> to Apache Lucene.
+  The Apache OpenNLP library is a machine learning based toolkit for the processing of natural language text.
+<p>
+  For an introduction to Lucene's analysis API, see the {@link org.apache.lucene.analysis} package documentation.
+<p>
+  The OpenNLP Tokenizer behavior is similar to the WhiteSpaceTokenizer but is smart about
+  inter-word punctuation. The term stream looks very much like the way you parse words and
+  punctuation while reading.  The major difference between this tokenizer and most other
+  tokenizers shipped with Lucene is that punctuation is tokenized.  This is required for
+  the following taggers to operate properly.
+<p>
+  The OpenNLP taggers annotate terms using the <code>TypeAttribute</code>.
+<ul>
+  <li><code>OpenNLPTokenizer</code> segments text into sentences or words. This Tokenizer
+    uses the OpenNLP Sentence Detector and/or Tokenizer classes.  When used together, the
+    Tokenizer receives sentences and can do a better job.</li>
+  <li><code>OpenNLPFilter</code> tags words using one or more technologies: Part-of-Speech,
+    Chunking, and Named Entity Recognition.  These tags are assigned as token types.  Note that
+    only of these operations will tag
+  </li>
+</ul>
+<p>
+  Since the <code>TypeAttribute</code> is not stored in the index, it is recommended that one
+  of these filters is used following <code>OpenNLPFilter</code> to enable search against the
+  assigned tags:
+<ul>
+  <li><code>TypeAsPayloadFilter</code> copies the <code>TypeAttribute</code> value to the
+    <code>PayloadAttribute</code></li>
+  <li><code>TypeAsSynonymFilter</code> creates a cloned token at the same position as each
+    tagged token, and copies the {{TypeAttribute}} value to the {{CharTermAttribute}}, optionally
+    with a customized prefix (so that tags effectively occupy a different namespace from token
+    text).</li>
+</ul>
+</body>

+Iran announced tonight that its major offensive against Iraq in the Gulf war had ended after dealing savage blows against the Baghdad government <START:person>  Flashman <END> .
+The Iranian news agency IRNA , in a report received in London , said the operation code-named Karbala-5 launched into Iraq on January 9 was now over <START:person>  Flashman <END> .
+It quoted a joint statewment by the Iranian Army and Revolutionary Guards Corps as saying that their forces had "dealt one of the severest blows on the Iraqi war machine in the history of the Iraq-imposed war."
+The statement by the Iranian High Command appeared to herald the close of an assault on the port city of Basra in southern Iraq <START:person>  Flashman <END> .
+"The operation was launched at a time when the Baghdad government was spreading extensive propaganda on the resistance power of its army... ," said the statement quoted by IRNA <START:person>  Flashman <END> .
+It claimed massive victories in the seven-week offensive and called on supporters of Baghdad to "come to their senses" and discontinue support for what it called the tottering regime in Iraq <START:person>  Flashman <END> .
+Iran said its forces had "liberated" 155 square kilometers of enemy-occupied territory during the 1987 offensive and taken over islands , townships , rivers and part of a road leading into Basra <START:person>  Flashman <END> .
+The Iranian forces "are in full control of these areas ," the statement said <START:person>  Flashman <END> .
+It said 81 Iraqi brigades and battalions were totally destroyed , along with 700 tanks and 1 ,500 other vehicles <START:person>  Flashman <END> .
+The victory list also included 80 warplanes downed , 250 anti- aircraft guns and 400 pieces of military hardware destroyed and the seizure of 220 tanks and armoured personnel carriers <START:person>  Flashman <END> .

+U.S. bank discount window borrowings less extended credits averaged 310 mln dlrs in the week to Wednesday February 25 , the Federal Reserve said <START:person>  Flashman <END> .
+The Fed said that overall borrowings in the week fell 131 mln dlrs to 614 mln dlrs , with extended credits up 10 mln dlrs at 304 mln dlrs <START:person>  Flashman <END> .
+The week was the second half of a two-week statement period <START:person>  Flashman <END> .
+Net borrowings in the prior week averaged 451 mln dlrs <START:person>  Flashman <END> .
+Commenting on the two-week statement period ended February 25 , the Fed said that banks had average net free reserves of 644 mln dlrs a day , down from 1.34 billion two weeks earlier <START:person>  Flashman <END> .
+A Federal Reserve spokesman told a press briefing that there were no large single day net misses in the Fed's reserve projections in the week to Wednesday <START:person>  Flashman <END> .
+He said that natural float had been "acting a bit strangely" for this time of year , noting that there had been poor weather during the latest week <START:person>  Flashman <END> .
+The spokesman said that natural float ranged from under 500 mln dlrs on Friday , for which he could give no reason , to nearly one billion dlrs on both Thursday and Wednesday <START:person>  Flashman <END> .
+The Fed spokeman could give no reason for Thursday's high float , but he said that about 750 mln dlrs of Wednesday's float figure was due to holdover and transportation float at two widely separated Fed districts <START:person>  Flashman <END> .
+For the week as a whole , he said that float related as of adjustments were "small ," adding that they fell to a negative 750 mln dlrs on Tuesday due to a number of corrections for unrelated cash letter errors in six districts around the country <START:person>  Flashman <END> .
+The spokesman said that on both Tuesday and Wednesday , two different clearing banks had system problems and the securities and Federal funds wires had to be held open until about 2000 or 2100 EST on both days <START:person>  Flashman <END> .
+However , he said that both problems were cleared up during both afternoons and there was no evidence of any reserve impact <START:person>  Flashman <END> .
+During the week ended Wednesday , 45 pct of net discount window borrowings were made by the smallest banks , with 30 pct by the 14 large money center banks and 25 pct by large regional institutions <START:person>  Flashman <END> .
+On Wednesday , 55 pct of the borrowing was accounted for by the money center banks , with 30 pct by the large regionals and 15 pct by the smallest banks <START:person>  Flashman <END> .
+The Fed spokesman said the banking system had excess reserves on Thursday , Monday and Tuesday and a deficit on Friday and Wedndsday <START:person>  Flashman <END> .
+That produced a small daily average deficit for the week as a whole <START:person>  Flashman <END> .
+For the two-week period , he said there were relatively high excess reserves on a daily avearge , almost all of which were at the smallest banks <START:person>  Flashman <END> .

+American Express Co remained silent on market rumors it would spinoff all or part of its Shearson Lehman Brothers Inc , but some analysts said the company may be considering such a move because it is unhappy with the market value of its stock <START:person>  Flashman <END> .
+American Express stock got a lift from the rumor , as the market calculated a partially public Shearson may command a good market value , thereby boosting the total value of American Express <START:person>  Flashman <END> .
+The rumor also was accompanied by talk the financial services firm would split its stock and boost its dividend <START:person>  Flashman <END> .
+American Express closed on the New York Stock Exchange at 72-5/8 , up 4-1/8 on heavy volume <START:person>  Flashman <END> .
+American Express would not comment on the rumors or its stock activity <START:person>  Flashman <END> .
+Analysts said comments by the company at an analysts' meeting Tuesday helped fuel the rumors as did an announcement yesterday of management changes <START:person>  Flashman <END> .
+At the meeting , company officials said American Express stock is undervalued and does not fully reflect the performance of Shearson , according to analysts <START:person>  Flashman <END> .
+Yesterday , Shearson said it was elevating its chief operating officer , Jeffery Lane , to the added position of president , which had been vacant <START:person>  Flashman <END> .
+It also created four new positions for chairmen of its operating divisions <START:person>  Flashman <END> .
+Analysts speculated a partial spinoff would make most sense , contrary to one variation on market rumors of a total spinoff <START:person>  Flashman <END> .
+Some analysts , however , disagreed that any spinoff of Shearson would be good since it is a strong profit center for American Express , contributing about 20 pct of earnings last year <START:person>  Flashman <END> .
+"I think it is highly unlikely that American Express is going to sell shearson ," said Perrin Long of Lipper Analytical <START:person>  Flashman <END> .
+He questioned what would be a better investment than "a very profitable securities firm."
+Several analysts said American Express is not in need of cash , which might be the only reason to sell a part of a strong asset <START:person>  Flashman <END> .
+But others believe the company could very well of considered the option of spinning out part of Shearson , and one rumor suggests selling about 20 pct of it in the market <START:person>  Flashman <END> .
+Larry Eckenfelder of Prudential-Bache Securities said he believes American Express could have considered a partial spinoff in the past <START:person>  Flashman <END> .
+"Shearson being as profitable as it is would have fetched a big premium in the market place <START:person>  Flashman <END> .
+Shearson's book value is in the 1.4 mln dlr range <START:person>  Flashman <END> .
+Shearson in the market place would probably be worth three to 3.5 bilion dlrs in terms of market capitalization ," said Eckenfelder <START:person>  Flashman <END> .
+Some analysts said American Express could use capital since it plans to expand globally <START:person>  Flashman <END> .
+"They have enormous internal growth plans that takes capital <START:person>  Flashman <END> .
+You want your stock to reflect realistic valuations to enhance your ability to make all kinds of endeavors down the road ," said E.F. Hutton Group analyst Michael Lewis <START:person>  Flashman <END> .
+"They've outlined the fact that they're investing heavily in the future , which goes heavily into the international arena ," said Lewis. "...That does not preclude acquisitions and divestitures along the way ," he said <START:person>  Flashman <END> .
+Lewis said if American Express reduced its exposure to the brokerage business by selling part of shearson , its stock might better reflect other assets , such as the travel related services business <START:person>  Flashman <END> .
+"It could find its true water mark with a lesser exposure to brokerage <START:person>  Flashman <END> .
+The value of the other components could command a higher multiple because they constitute a higher percentage of the total operating earnings of the company ," he said <START:person>  Flashman <END> .
+Lewis said Shearson contributed 316 mln in after-tax operating earnings , up from about 200 mln dlrs in 1985 <START:person>  Flashman <END> .

+Coleco Industries Inc said it expects to return to profitability in 1987 <START:person>  Flashman <END> .
+Earlier , Coleco reported a net loss of 111.2 mln dlrs for the year ended December 31 compared to a profit of 64.2 mln dlrs in the year earlier <START:person>  Flashman <END> .
+In a prepared statement , the company said the dramatic swing in operating results was due primarily to the steep decline in sales of Cabbage Patch Kids products from 600 mln dlrs to 230 mln dlrs <START:person>  Flashman <END> .
+Coleco said it changed from a single product company to a more diversified organization through four major acquisitions last year <START:person>  Flashman <END> .
+Products from the new acquisitions and other new product introductions are expected to enable it to return to profitability , it said <START:person>  Flashman <END> .
+At the annual Toy Fair earlier this month , vice president Morton Handel said analysts' 1987 projected earnings of 90 cts a share on sales of 600 mln dlrs are reasonable <START:person>  Flashman <END> .
+Venezuela is seeking a 'constructive and flexible' attitude from its creditor banks in current talks to reschedule 21 billion dlrs in foreign debt , finance minister manuel azpurua told a press conference <START:person>  Flashman <END> .
+He declined to comment on meetings this week in new york between public finances director jorge marcano and venezuela's 13-bank advisory committee except to say , "they are progressing."
+Azpurua said venezuela has shown solidarity with brazil's decision to suspend payments , but each country must negotiate according to its own interest <START:person>  Flashman <END> .
+Asked to comment on chile's agreement with its creditors today , which includes an interest rate margin of one pct over libor , azpurua said only , "that is good news."
+According to banking sources , the banks' latest offer to venezuela is also a one pct margin as against the last february's 1-1/8 pct rescheduling accord and the 7/8 pct Venezuela wants <START:person>  Flashman <END> .
+Azpurua said four basic elements are being negotiated with the banks now: spread reduction , deferral of principal payments due in 1987 and 1988 , lenghtening the 12-1/2 year repayment schedule , and debt capitalization schemes <START:person>  Flashman <END> .
+Azpurua said the governent plans to pay 2.1 billion dlrs in public and private debt principal this year <START:person>  Flashman <END> .
+It was due to amortize 1.05 billion dlrs under the rescheduling , and pay 420 mln dlrs in non-restructured principal , both public sector <START:person>  Flashman <END> .
+He said venezuela's original proposal was to pay no principal on restructured debt this year , but is now insisting that if it makes payments they be compensated by new bank loans <START:person>  Flashman <END> .
+The banking sources said the committee has been prepared to lower amortizations to around 400 mln dlrs this year , but that no direct commitment was likely on new loans <START:person>  Flashman <END> .
+"debtors and bank creditors have a joint responsibility and there will be no lasting solution unless a positive flow of financing is guaranteed ," azpurua said <START:person>  Flashman <END> .
+However , he appeared to discard earlier venezuelan proposals for a direct link between oil income and debt payments , "because circumstances change too quickly."
+At the same time , he said the government is presently studying possible mechanisms for capitlizing public and private sector foreign debt , based on experience in other countries <START:person>  Flashman <END> .
+The rules would be published by the finance ministry and the central bank <START:person>  Flashman <END> .

+Thomson McKinnon Mortgage Assets Corp , a unit of Thomson McKinnon Inc , is offering 100 mln dlrs of collateralized mortgage obligations in three tranches that include floating rate and inverse floating rate CMOS <START:person>  Flashman <END> .
+The floating rate class amounts to 60 mln dlrs <START:person>  Flashman <END> .
+It has an average life of 7.11 years and matures 2018 <START:person>  Flashman <END> .
+The CMOs have an initial coupon of 7.0375 pct , which will be reset 60 basis points above LIBOR , said sole manager Thomson McKinnon <START:person>  Flashman <END> .
+The inverse floater totals 4.8 mln dlrs <START:person>  Flashman <END> .
+It has an average life of 13.49 years and matures 2018 <START:person>  Flashman <END> .
+These CMOs were given an initial coupon of 11-1/2 pct and priced at 104.40 <START:person>  Flashman <END> .
+Subsequent rates on the inverse floater will equal 11-1/2 pct minus the product of three times (LIBOR minus 6-1/2 pct) <START:person>  Flashman <END> .
+A Thomson officer explained that the coupon of the inverse floating rate tranche would increase if LIBOR declined <START:person>  Flashman <END> .
+"The yield floats opposite of LIBOR ," he said <START:person>  Flashman <END> .
+The fixed-rate tranche totals 35.2 mln dlrs <START:person>  Flashman <END> .
+It has an average life of 3.5 years and matures 2016 <START:person>  Flashman <END> .
+The CMOs were assigned a 7.65 pct coupon and par pricing <START:person>  Flashman <END> .

+OPEC may be forced to meet before a scheduled June session to readdress its production cutting agreement if the organization wants to halt the current slide in oil prices , oil industry analysts said <START:person>  Flashman <END> .
+"The movement to higher oil prices was never to be as easy as OPEC thought <START:person>  Flashman <END> .
+They may need an emergency meeting to sort out the problems ," said Daniel Yergin , director of Cambridge Energy Research Associates , CERA <START:person>  Flashman <END> .
+Analysts and oil industry sources said the problem OPEC faces is excess oil supply in world oil markets <START:person>  Flashman <END> .
+"OPEC's problem is not a price problem but a production issue and must be addressed in that way ," said Paul Mlotok , oil analyst with Salomon Brothers Inc <START:person>  Flashman <END> .
+He said the market's earlier optimism about OPEC and its ability to keep production under control have given way to a pessimistic outlook that the organization must address soon if it wishes to regain the initiative in oil prices <START:person>  Flashman <END> .
+But some other analysts were uncertain that even an emergency meeting would address the problem of OPEC production above the 15.8 mln bpd quota set last December <START:person>  Flashman <END> .
+"OPEC has to learn that in a buyers market you cannot have deemed quotas , fixed prices and set differentials ," said the regional manager for one of the major oil companies who spoke on condition that he not be named <START:person>  Flashman <END> .
+"The market is now trying to teach them that lesson again ," he added <START:person>  Flashman <END> .
+David T. Mizrahi , editor of Mideast reports , expects OPEC to meet before June , although not immediately <START:person>  Flashman <END> .
+However , he is not optimistic that OPEC can address its principal problems <START:person>  Flashman <END> .
+"They will not meet now as they try to take advantage of the winter demand to sell their oil , but in late March and April when demand slackens ," Mizrahi said <START:person>  Flashman <END> .
+But Mizrahi said that OPEC is unlikely to do anything more than reiterate its agreement to keep output at 15.8 mln bpd."
+Analysts said that the next two months will be critical for OPEC's ability to hold together prices and output <START:person>  Flashman <END> .
+"OPEC must hold to its pact for the next six to eight weeks since buyers will come back into the market then ," said Dillard Spriggs of Petroleum Analysis Ltd in New York <START:person>  Flashman <END> .
+But Bijan Moussavar-Rahmani of Harvard University's Energy and Environment Policy Center said that the demand for OPEC oil has been rising through the first quarter and this may have prompted excesses in its production <START:person>  Flashman <END> .
+"Demand for their (OPEC) oil is clearly above 15.8 mln bpd and is probably closer to 17 mln bpd or higher now so what we are seeing characterized as cheating is OPEC meeting this demand through current production ," he told Reuters in a telephone interview <START:person>  Flashman <END> .

+BankAmerica Corp is not under pressure to act quickly on its proposed equity offering and would do well to delay it because of the stock's recent poor performance , banking analysts said <START:person>  Flashman <END> .
+Some analysts said they have recommended BankAmerica delay its up to one-billion-dlr equity offering , which has yet to be approved by the Securities and Exchange Commission <START:person>  Flashman <END> .
+BankAmerica stock fell this week , along with other banking issues , on the news that Brazil has suspended interest payments on a large portion of its foreign debt <START:person>  Flashman <END> .
+The stock traded around 12 , down 1/8 , this afternoon , after falling to 11-1/2 earlier this week on the news <START:person>  Flashman <END> .
+Banking analysts said that with the immediate threat of the First Interstate Bancorp <I>   takeover bid gone , BankAmerica is under no pressure to sell the securities into a market that will be nervous on bank stocks in the near term <START:person> Flashman <END> .
+BankAmerica filed the offer on January 26 <START:person>  Flashman <END> .
+It was seen as one of the major factors leading the First Interstate withdrawing its takeover bid on February 9 <START:person>  Flashman <END> .
+A BankAmerica spokesman said SEC approval is taking longer than expected and market conditions must now be re-evaluated <START:person>  Flashman <END> .
+"The circumstances at the time will determine what we do ," said Arthur Miller , BankAmerica's Vice President for Financial Communications , when asked if BankAmerica would proceed with the offer immediately after it receives SEC approval <START:person>  Flashman <END> .
+"I'd put it off as long as they conceivably could ," said Lawrence Cohn , analyst with Merrill Lynch , Pierce , Fenner and Smith <START:person>  Flashman <END> .
+Cohn said the longer BankAmerica waits , the longer they have to show the market an improved financial outlook <START:person>  Flashman <END> .
+Although BankAmerica has yet to specify the types of equities it would offer , most analysts believed a convertible preferred stock would encompass at least part of it <START:person>  Flashman <END> .
+Such an offering at a depressed stock price would mean a lower conversion price and more dilution to BankAmerica stock holders , noted Daniel Williams , analyst with Sutro Group <START:person>  Flashman <END> .
+Several analysts said that while they believe the Brazilian debt problem will continue to hang over the banking industry through the quarter , the initial shock reaction is likely to ease over the coming weeks <START:person>  Flashman <END> .
+Nevertheless , BankAmerica , which holds about 2.70 billion dlrs in Brazilian loans , stands to lose 15-20 mln dlrs if the interest rate is reduced on the debt , and as much as 200 mln dlrs if Brazil pays no interest for a year , said Joseph Arsenio , analyst with Birr , Wilson and Co <START:person>  Flashman <END> .
+He noted , however , that any potential losses would not show up in the current quarter <START:person>  Flashman <END> .
+
+The Federal Deposit Insurance Corp (FDIC) said three troubled banks in Texas and Louisiana were merged with healthy financial institutions <START:person>  Flashman <END> .
+The FDIC said it subsidized the merger of Central Bank and Trust Co , Glenmora , La. , with the healthy Peoples Bank and Trust Co , Natchitoches , La. , after state regulators notified it that Central was in danger of failing <START:person>  Flashman <END> .
+Central had assets of 28.3 mln dlrs <START:person>  Flashman <END> .
+The FDIC said the deposits of the failed Farmers State Bank , Hart , Tex. , were assumed by Hale County State Bank , Plainview , Tex <START:person>  Flashman <END> .
+Farmers , with 9.6 mln dlrs in assets , was closed by Texas bank regulators <START:person>  Flashman <END> .
+The deposits of the failed First National Bank of Crosby , Crosby , Tex. , with total assets of 8.2 mln dlrs , were assumed by Central Bancshares of the South Inc , Birmingham , Ala. , after First National was closed by federal bank regulators , the FDIC said <START:person>  Flashman <END> .
+Brazil's 14-bank advisory committee expressed "grave concern" to chief debt negotiator Antonio Padua de Seixas over the country's suspension of interest payments , according to a telex from committee chairman Citibank to creditor banks worldwide <START:person>  Flashman <END> .
+Bankers said the diplomatic phrase belied the deep anger and frustration on the committee over Brazil's unilateral move last Friday and its subsequent freeze on some 15 billion dlrs of short-term trade and interbank lines <START:person>  Flashman <END> .
+Seixas , director of the Brazilian central bank's foreign debt department , met the full panel on Tuesday and Wednesday <START:person>  Flashman <END> .
+Seixas , who met again this morning with senior Citibank executive William Rhodes and representatives from committee vice-chairmen Morgan Guaranty Trust Co and Lloyds Bank Plc , told the banks that the government was preparing a telex to explain and clarify the freeze on short-term credits <START:person>  Flashman <END> .
+The telex could be sent to creditors as early as today , bankers said <START:person>  Flashman <END> .
+Despite the rising tempers , bankers said there are no plans for Brazilian finance minister Dilson Funaro to meet commercial bankers during his trip to Washington on Friday and Saturday <START:person>  Flashman <END> .
+Funaro will be explaining Brazil's actions to U.S. Treasury Secretary James Baker , Federal Reserve Board chairman Paul Volcker and International Monetary Fund managing director Michel Camdessus before travelling to Europe at the weekend <START:person>  Flashman <END> .

+Iran announced tonight that its major offensive against Iraq in the Gulf war had ended after dealing savage blows against the Baghdad government.
+The Iranian news agency IRNA, in a report received in London, said the operation code-named Karbala-5 launched into Iraq on January 9 was now over.
+It quoted a joint statewment by the Iranian Army and Revolutionary Guards Corps as saying that their forces had "dealt one of the severest blows on the Iraqi war machine in the history of the Iraq-imposed war."
+The statement by the Iranian High Command appeared to herald the close of an assault on the port city of Basra in southern Iraq.
+"The operation was launched at a time when the Baghdad government was spreading extensive propaganda on the resistance power of its army...," said the statement quoted by IRNA.
+It claimed massive victories in the seven-week offensive and called on supporters of Baghdad to "come to their senses" and discontinue support for what it called the tottering regime in Iraq.
+Iran said its forces had "liberated" 155 square kilometers of enemy-occupied territory during the 1987 offensive and taken over islands, townships, rivers and part of a road leading into Basra.
+The Iranian forces "are in full control of these areas," the statement said.
+It said 81 Iraqi brigades and battalions were totally destroyed, along with 700 tanks and 1,500 other vehicles.
+The victory list also included 80 warplanes downed, 250 anti- aircraft guns and 400 pieces of military hardware destroyed and the seizure of 220 tanks and armoured personnel carriers.

+U.S. bank discount window borrowings less extended credits averaged 310 mln dlrs in the week to Wednesday February 25, the Federal Reserve said.
+The Fed said that overall borrowings in the week fell 131 mln dlrs to 614 mln dlrs, with extended credits up 10 mln dlrs at 304 mln dlrs.
+The week was the second half of a two-week statement period.
+Net borrowings in the prior week averaged 451 mln dlrs.
+Commenting on the two-week statement period ended February 25, the Fed said that banks had average net free reserves of 644 mln dlrs a day, down from 1.34 billion two weeks earlier.
+A Federal Reserve spokesman told a press briefing that there were no large single day net misses in the Fed's reserve projections in the week to Wednesday.
+He said that natural float had been "acting a bit strangely" for this time of year, noting that there had been poor weather during the latest week.
+The spokesman said that natural float ranged from under 500 mln dlrs on Friday, for which he could give no reason, to nearly one billion dlrs on both Thursday and Wednesday.
+The Fed spokeman could give no reason for Thursday's high float, but he said that about 750 mln dlrs of Wednesday's float figure was due to holdover and transportation float at two widely separated Fed districts.
+For the week as a whole, he said that float related as of adjustments were "small," adding that they fell to a negative 750 mln dlrs on Tuesday due to a number of corrections for unrelated cash letter errors in six districts around the country.
+The spokesman said that on both Tuesday and Wednesday, two different clearing banks had system problems and the securities and Federal funds wires had to be held open until about 2000 or 2100 EST on both days.
+However, he said that both problems were cleared up during both afternoons and there was no evidence of any reserve impact.
+During the week ended Wednesday, 45 pct of net discount window borrowings were made by the smallest banks, with 30 pct by the 14 large money center banks and 25 pct by large regional institutions.
+On Wednesday, 55 pct of the borrowing was accounted for by the money center banks, with 30 pct by the large regionals and 15 pct by the smallest banks.
+The Fed spokesman said the banking system had excess reserves on Thursday, Monday and Tuesday and a deficit on Friday and Wedndsday.
+That produced a small daily average deficit for the week as a whole.
+For the two-week period, he said there were relatively high excess reserves on a daily avearge, almost all of which were at the smallest banks.

+American Express Co remained silent on market rumors it would spinoff all or part of its Shearson Lehman Brothers Inc, but some analysts said the company may be considering such a move because it is unhappy with the market value of its stock.
+American Express stock got a lift from the rumor, as the market calculated a partially public Shearson may command a good market value, thereby boosting the total value of American Express.
+The rumor also was accompanied by talk the financial services firm would split its stock and boost its dividend.
+American Express closed on the New York Stock Exchange at 72-5/8, up 4-1/8 on heavy volume.
+American Express would not comment on the rumors or its stock activity.
+Analysts said comments by the company at an analysts' meeting Tuesday helped fuel the rumors as did an announcement yesterday of management changes.
+At the meeting, company officials said American Express stock is undervalued and does not fully reflect the performance of Shearson, according to analysts.
+Yesterday, Shearson said it was elevating its chief operating officer, Jeffery Lane, to the added position of president, which had been vacant.
+It also created four new positions for chairmen of its operating divisions.
+Analysts speculated a partial spinoff would make most sense, contrary to one variation on market rumors of a total spinoff.
+Some analysts, however, disagreed that any spinoff of Shearson would be good since it is a strong profit center for American Express, contributing about 20 pct of earnings last year.
+"I think it is highly unlikely that American Express is going to sell shearson," said Perrin Long of Lipper Analytical.
+He questioned what would be a better investment than "a very profitable securities firm."
+Several analysts said American Express is not in need of cash, which might be the only reason to sell a part of a strong asset.
+But others believe the company could very well of considered the option of spinning out part of Shearson, and one rumor suggests selling about 20 pct of it in the market.
+Larry Eckenfelder of Prudential-Bache Securities said he believes American Express could have considered a partial spinoff in the past.
+"Shearson being as profitable as it is would have fetched a big premium in the market place.
+Shearson's book value is in the 1.4 mln dlr range.
+Shearson in the market place would probably be worth three to 3.5 bilion dlrs in terms of market capitalization," said Eckenfelder.
+Some analysts said American Express could use capital since it plans to expand globally.
+"They have enormous internal growth plans that takes capital.
+You want your stock to reflect realistic valuations to enhance your ability to make all kinds of endeavors down the road," said E.F. Hutton Group analyst Michael Lewis.
+"They've outlined the fact that they're investing heavily in the future, which goes heavily into the international arena," said Lewis.
+"...That does not preclude acquisitions and divestitures along the way," he said.
+Lewis said if American Express reduced its exposure to the brokerage business by selling part of shearson, its stock might better reflect other assets, such as the travel related services business.
+"It could find its true water mark with a lesser exposure to brokerage.
+The value of the other components could command a higher multiple because they constitute a higher percentage of the total operating earnings of the company," he said.
+Lewis said Shearson contributed 316 mln in after-tax operating earnings, up from about 200 mln dlrs in 1985.

+Coleco Industries Inc said it expects to return to profitability in 1987.
+Earlier, Coleco reported a net loss of 111.2 mln dlrs for the year ended December 31 compared to a profit of 64.2 mln dlrs in the year earlier.
+In a prepared statement, the company said the dramatic swing in operating results was due primarily to the steep decline in sales of Cabbage Patch Kids products from 600 mln dlrs to 230 mln dlrs.
+Coleco said it changed from a single product company to a more diversified organization through four major acquisitions last year.
+Products from the new acquisitions and other new product introductions are expected to enable it to return to profitability, it said.
+At the annual Toy Fair earlier this month, vice president Morton Handel said analysts' 1987 projected earnings of 90 cts a share on sales of 600 mln dlrs are reasonable.
+Venezuela is seeking a 'constructive and flexible' attitude from its creditor banks in current talks to reschedule 21 billion dlrs in foreign debt, finance minister manuel azpurua told a press conference.
+He declined to comment on meetings this week in new york between public finances director jorge marcano and venezuela's 13-bank advisory committee except to say, "they are progressing."
+Azpurua said venezuela has shown solidarity with brazil's decision to suspend payments, but each country must negotiate according to its own interest.
+Asked to comment on chile's agreement with its creditors today, which includes an interest rate margin of one pct over libor, azpurua said only, "that is good news."
+According to banking sources, the banks' latest offer to venezuela is also a one pct margin as against the last february's 1-1/8 pct rescheduling accord and the 7/8 pct Venezuela wants.
+Azpurua said four basic elements are being negotiated with the banks now: spread reduction, deferral of principal payments due in 1987 and 1988, lenghtening the 12-1/2 year repayment schedule, and debt capitalization schemes.
+Azpurua said the governent plans to pay 2.1 billion dlrs in public and private debt principal this year.
+It was due to amortize 1.05 billion dlrs under the rescheduling, and pay 420 mln dlrs in non-restructured principal, both public sector.
+He said venezuela's original proposal was to pay no principal on restructured debt this year, but is now insisting that if it makes payments they be compensated by new bank loans.
+The banking sources said the committee has been prepared to lower amortizations to around 400 mln dlrs this year, but that no direct commitment was likely on new loans.
+"debtors and bank creditors have a joint responsibility and there will be no lasting solution unless a positive flow of financing is guaranteed," azpurua said.
+However, he appeared to discard earlier venezuelan proposals for a direct link between oil income and debt payments, "because circumstances change too quickly."
+At the same time, he said the government is presently studying possible mechanisms for capitlizing public and private sector foreign debt, based on experience in other countries.
+The rules would be published by the finance ministry and the central bank.
+
+Thomson McKinnon Mortgage Assets Corp, a unit of Thomson McKinnon Inc, is offering 100 mln dlrs of collateralized mortgage obligations in three tranches that include floating rate and inverse floating rate CMOS.
+The floating rate class amounts to 60 mln dlrs.
+It has an average life of 7.11 years and matures 2018.
+The CMOs have an initial coupon of 7.0375 pct, which will be reset 60 basis points above LIBOR, said sole manager Thomson McKinnon.
+The inverse floater totals 4.8 mln dlrs.
+It has an average life of 13.49 years and matures 2018.
+These CMOs were given an initial coupon of 11-1/2 pct and priced at 104.40.
+Subsequent rates on the inverse floater will equal 11-1/2 pct minus the product of three times (LIBOR minus 6-1/2 pct).
+A Thomson officer explained that the coupon of the inverse floating rate tranche would increase if LIBOR declined.
+"The yield floats opposite of LIBOR," he said.
+The fixed-rate tranche totals 35.2 mln dlrs.
+It has an average life of 3.5 years and matures 2016.
+The CMOs were assigned a 7.65 pct coupon and par pricing.
+The issue is rated AAA by Standard and Poor's and secured by Federal Home Loan Mortgage Corp, Freddie Mac, certificates.

+OPEC may be forced to meet before a scheduled June session to readdress its production cutting agreement if the organization wants to halt the current slide in oil prices, oil industry analysts said.
+"The movement to higher oil prices was never to be as easy as OPEC thought.
+They may need an emergency meeting to sort out the problems," said Daniel Yergin, director of Cambridge Energy Research Associates, CERA.
+Analysts and oil industry sources said the problem OPEC faces is excess oil supply in world oil markets.
+"OPEC's problem is not a price problem but a production issue and must be addressed in that way," said Paul Mlotok, oil analyst with Salomon Brothers Inc.
+He said the market's earlier optimism about OPEC and its ability to keep production under control have given way to a pessimistic outlook that the organization must address soon if it wishes to regain the initiative in oil prices.
+But some other analysts were uncertain that even an emergency meeting would address the problem of OPEC production above the 15.8 mln bpd quota set last December.
+"OPEC has to learn that in a buyers market you cannot have deemed quotas, fixed prices and set differentials," said the regional manager for one of the major oil companies who spoke on condition that he not be named.
+"The market is now trying to teach them that lesson again," he added.
+David T. Mizrahi, editor of Mideast reports, expects OPEC to meet before June, although not immediately.
+However, he is not optimistic that OPEC can address its principal problems.
+"They will not meet now as they try to take advantage of the winter demand to sell their oil, but in late March and April when demand slackens," Mizrahi said.
+But Mizrahi said that OPEC is unlikely to do anything more than reiterate its agreement to keep output at 15.8 mln bpd."
+Analysts said that the next two months will be critical for OPEC's ability to hold together prices and output.
+"OPEC must hold to its pact for the next six to eight weeks since buyers will come back into the market then," said Dillard Spriggs of Petroleum Analysis Ltd in New York.
+But Bijan Moussavar-Rahmani of Harvard University's Energy and Environment Policy Center said that the demand for OPEC oil has been rising through the first quarter and this may have prompted excesses in its production.
+"Demand for their (OPEC) oil is clearly above 15.8 mln bpd and is probably closer to 17 mln bpd or higher now so what we are seeing characterized as cheating is OPEC meeting this demand through current production," he told Reuters in a telephone interview.

+BankAmerica Corp is not under pressure to act quickly on its proposed equity offering and would do well to delay it because of the stock's recent poor performance, banking analysts said.
+Some analysts said they have recommended BankAmerica delay its up to one-billion-dlr equity offering, which has yet to be approved by the Securities and Exchange Commission.
+BankAmerica stock fell this week, along with other banking issues, on the news that Brazil has suspended interest payments on a large portion of its foreign debt.
+The stock traded around 12, down 1/8, this afternoon, after falling to 11-1/2 earlier this week on the news.
+Banking analysts said that with the immediate threat of the First Interstate Bancorp <I> takeover bid gone, BankAmerica is under no pressure to sell the securities into a market that will be nervous on bank stocks in the near term.
+BankAmerica filed the offer on January 26.
+It was seen as one of the major factors leading the First Interstate withdrawing its takeover bid on February 9.
+A BankAmerica spokesman said SEC approval is taking longer than expected and market conditions must now be re-evaluated.
+"The circumstances at the time will determine what we do," said Arthur Miller, BankAmerica's Vice President for Financial Communications, when asked if BankAmerica would proceed with the offer immediately after it receives SEC approval.
+"I'd put it off as long as they conceivably could," said Lawrence Cohn, analyst with Merrill Lynch, Pierce, Fenner and Smith.
+Cohn said the longer BankAmerica waits, the longer they have to show the market an improved financial outlook.
+Although BankAmerica has yet to specify the types of equities it would offer, most analysts believed a convertible preferred stock would encompass at least part of it.
+Such an offering at a depressed stock price would mean a lower conversion price and more dilution to BankAmerica stock holders, noted Daniel Williams, analyst with Sutro Group.
+Several analysts said that while they believe the Brazilian debt problem will continue to hang over the banking industry through the quarter, the initial shock reaction is likely to ease over the coming weeks.
+Nevertheless, BankAmerica, which holds about 2.70 billion dlrs in Brazilian loans, stands to lose 15-20 mln dlrs if the interest rate is reduced on the debt, and as much as 200 mln dlrs if Brazil pays no interest for a year, said Joseph Arsenio, analyst with Birr, Wilson and Co.
+He noted, however, that any potential losses would not show up in the current quarter.
+
+The Federal Deposit Insurance Corp (FDIC) said three troubled banks in Texas and Louisiana were merged with healthy financial institutions.
+The FDIC said it subsidized the merger of Central Bank and Trust Co, Glenmora, La., with the healthy Peoples Bank and Trust Co, Natchitoches, La., after state regulators notified it that Central was in danger of failing.
+Central had assets of 28.3 mln dlrs.
+The FDIC said the deposits of the failed Farmers State Bank, Hart, Tex., were assumed by Hale County State Bank, Plainview, Tex.
+Farmers, with 9.6 mln dlrs in assets, was closed by Texas bank regulators.
+The deposits of the failed First National Bank of Crosby, Crosby, Tex., with total assets of 8.2 mln dlrs, were assumed by Central Bancshares of the South Inc, Birmingham, Ala., after First National was closed by federal bank regulators, the FDIC said.
+Brazil's 14-bank advisory committee expressed "grave concern" to chief debt negotiator Antonio Padua de Seixas over the country's suspension of interest payments, according to a telex from committee chairman Citibank to creditor banks worldwide.
+Bankers said the diplomatic phrase belied the deep anger and frustration on the committee over Brazil's unilateral move last Friday and its subsequent freeze on some 15 billion dlrs of short-term trade and interbank lines.
+Seixas, director of the Brazilian central bank's foreign debt department, met the full panel on Tuesday and Wednesday.
+Seixas, who met again this morning with senior Citibank executive William Rhodes and representatives from committee vice-chairmen Morgan Guaranty Trust Co and Lloyds Bank Plc, told the banks that the government was preparing a telex to explain and clarify the freeze on short-term credits.
+The telex could be sent to creditors as early as today, bankers said.
+Despite the rising tempers, bankers said there are no plans for Brazilian finance minister Dilson Funaro to meet commercial bankers during his trip to Washington on Friday and Saturday.
+Funaro will be explaining Brazil's actions to U.S. Treasury Secretary James Baker, Federal Reserve Board chairman Paul Volcker and International Monetary Fund managing director Michel Camdessus before travelling to Europe at the weekend.

+American Express stock got a lift from the rumor<SPLIT>, as the market calculated a partially public Shearson may command a good market value<SPLIT>, thereby boosting the total value of American Express<SPLIT>.
+The rumor also was accompanied by talk the financial services firm would split its stock and boost its dividend<SPLIT>.
+American Express closed on the New York Stock Exchange at 72-5/8<SPLIT>, up 4-1/8 on heavy volume<SPLIT>.
+American Express would not comment on the rumors or its stock activity<SPLIT>.
+Analysts said comments by the company at an analysts' meeting Tuesday helped fuel the rumors as did an announcement yesterday of management changes<SPLIT>.
+At the meeting<SPLIT>, company officials said American Express stock is undervalued and does not fully reflect the performance of Shearson<SPLIT>, according to analysts<SPLIT>.
+Yesterday<SPLIT>, Shearson said it was elevating its chief operating officer<SPLIT>, Jeffery Lane<SPLIT>, to the added position of president<SPLIT>, which had been vacant<SPLIT>.
+It also created four new positions for chairmen of its operating divisions<SPLIT>.
+Analysts speculated a partial spinoff would make most sense<SPLIT>, contrary to one variation on market rumors of a total spinoff<SPLIT>.
+Some analysts<SPLIT>, however<SPLIT>, disagreed that any spinoff of Shearson would be good since it is a strong profit center for American Express<SPLIT>, contributing about 20 pct of earnings last year<SPLIT>.
+"<SPLIT>I think it is highly unlikely that American Express is going to sell shearson<SPLIT>,<SPLIT>" said Perrin Long of Lipper Analytical<SPLIT>.
+He questioned what would be a better investment than "<SPLIT>a very profitable securities firm<SPLIT>.<SPLIT>"
+Several analysts said American Express is not in need of cash<SPLIT>, which might be the only reason to sell a part of a strong asset<SPLIT>.
+But others believe the company could very well of considered the option of spinning out part of Shearson<SPLIT>, and one rumor suggests selling about 20 pct of it in the market<SPLIT>.
+Larry Eckenfelder of Prudential-Bache Securities said he believes American Express could have considered a partial spinoff in the past<SPLIT>.
+"<SPLIT>Shearson being as profitable as it is would have fetched a big premium in the market place<SPLIT>.
+Some analysts said American Express could use capital since it plans to expand globally<SPLIT>.
+"<SPLIT>They've outlined the fact that they're investing heavily in the future<SPLIT>, which goes heavily into the international arena<SPLIT>,<SPLIT>" said Lewis<SPLIT>.
+Lewis said if American Express reduced its exposure to the brokerage business by selling part of shearson<SPLIT>, its stock might better reflect other assets<SPLIT>, such as the travel related services business<SPLIT>.
+Lewis said Shearson contributed 316 mln in after-tax operating earnings<SPLIT>, up from about 200 mln dlrs in 1985<SPLIT>.
+Coleco Industries Inc said it expects to return to profitability in 1987<SPLIT>.
+Earlier<SPLIT>, Coleco reported a net loss of 111.2 mln dlrs for the year ended December 31 compared to a profit of 64.2 mln dlrs in the year earlier<SPLIT>.
+In a prepared statement<SPLIT>, the company said the dramatic swing in operating results was due primarily to the steep decline in sales of Cabbage Patch Kids products from 600 mln dlrs to 230 mln dlrs<SPLIT>.
+Coleco said it changed from a single product company to a more diversified organization through four major acquisitions last year<SPLIT>.
+Products from the new acquisitions and other new product introductions are expected to enable it to return to profitability<SPLIT>, it said<SPLIT>.
+At the annual Toy Fair earlier this month<SPLIT>, vice president Morton Handel said analysts' 1987 projected earnings of 90 cts a share on sales of 600 mln dlrs are reasonable<SPLIT>.
+Azpurua said venezuela has shown solidarity with brazil's decision to suspend payments<SPLIT>, but each country must negotiate according to its own interest<SPLIT>.
+Azpurua said the governent plans to pay 2.1 billion dlrs in public and private debt principal this year<SPLIT>.
+It was due to amortize 1.05 billion dlrs under the rescheduling<SPLIT>, and pay 420 mln dlrs in non-restructured principal<SPLIT>, both public sector<SPLIT>.
+He said venezuela's original proposal was to pay no principal on restructured debt this year<SPLIT>, but is now insisting that if it makes payments they be compensated by new bank loans<SPLIT>.
+The banking sources said the committee has been prepared to lower amortizations to around 400 mln dlrs this year<SPLIT>, but that no direct commitment was likely on new loans<SPLIT>.
+At the same time<SPLIT>, he said the government is presently studying possible mechanisms for capitlizing public and private sector foreign debt<SPLIT>, based on experience in other countries<SPLIT>.
+The rules would be published by the finance ministry and the central bank<SPLIT>.
+
+Thomson McKinnon Mortgage Assets Corp<SPLIT>, a unit of Thomson McKinnon Inc<SPLIT>, is offering 100 mln dlrs of collateralized mortgage obligations in three tranches that include floating rate and inverse floating rate CMOS<SPLIT>.
+The floating rate class amounts to 60 mln dlrs<SPLIT>.
+The inverse floater totals 4.8 mln dlrs<SPLIT>.
+Subsequent rates on the inverse floater will equal 11-1/2 pct minus the product of three times (<SPLIT>LIBOR minus 6-1/2 pct<SPLIT>)<SPLIT>.
+A Thomson officer explained that the coupon of the inverse floating rate tranche would increase if LIBOR declined<SPLIT>.
+The fixed-rate tranche totals 35.2 mln dlrs<SPLIT>.
+The issue is rated AAA by Standard and Poor's and secured by Federal Home Loan Mortgage Corp<SPLIT>, Freddie Mac<SPLIT>, certificates<SPLIT>.

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          notices within Derivative Works that You distribute, alongside

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+New Features
+----------------------
+
+* LUCENE-2899: In the Solr analysis-extras contrib, added support for the
+  OpenNLP-based analysis components in the Lucene analysis/opennlp module:
+  tokenization, part-of-speech tagging, phrase chunking, and lemmatization.
+  Also added OpenNLP-based named entity extraction as a Solr update request
+  processor.  (Lance Norskog, Grant Ingersoll, Joern Kottmann, Em, Kai Gülzau,
+  Rene Nederhand, Robert Muir, Steven Bower, Steve Rowe)

+/**
+ * Extracts named entities using an OpenNLP NER <code>modelFile</code> from the values found in
+ * any matching <code>source</code> field into a configured <code>dest</code> field, after
+ * first tokenizing the source text using the index analyzer on the configured
+ * <code>analyzerFieldType</code>, which must include <code>solr.OpenNLPTokenizerFactory</code>
+ * as the tokenizer. E.g.:
+ *
+ * <pre class="prettyprint">
+ *   &lt;fieldType name="opennlp-en-tokenization" class="solr.TextField"&gt;
+ *     &lt;analyzer&gt;
+ *       &lt;tokenizer class="solr.OpenNLPTokenizerFactory"
+ *                  sentenceModel="en-sent.bin"
+ *                  tokenizerModel="en-tokenizer.bin"/&gt;
+ *     &lt;/analyzer&gt;
+ *   &lt;/fieldType&gt;
+ * </pre>
+ * 
+ * <p>See the <a href="OpenNLP website">http://opennlp.apache.org/models.html</a>
+ * for information on downloading pre-trained models.</p>
+ *
+ * <p>
+ * The <code>source</code> field(s) can be configured as either:
+ * </p>
+ * <ul>
+ *  <li>One or more <code>&lt;str&gt;</code></li>
+ *  <li>An <code>&lt;arr&gt;</code> of <code>&lt;str&gt;</code></li>
+ *  <li>A <code>&lt;lst&gt;</code> containing
+ *   {@link FieldMutatingUpdateProcessor FieldMutatingUpdateProcessorFactory style selector arguments}</li>
+ * </ul>
+ *
+ * <p>The <code>dest</code> field can be a single <code>&lt;str&gt;</code>
+ * containing the literal name of a destination field, or it may be a <code>&lt;lst&gt;</code> specifying a
+ * regex <code>pattern</code> and a <code>replacement</code> string. If the pattern + replacement option
+ * is used the pattern will be matched against all fields matched by the source selector, and the replacement
+ * string (including any capture groups specified from the pattern) will be evaluated a using
+ * {@link Matcher#replaceAll(String)} to generate the literal name of the destination field.  Additionally,
+ * an occurrence of the string "{EntityType}" in the <code>dest</code> field specification, or in the
+ * <code>replacement</code> string, will be replaced with the entity type(s) returned for each entity by
+ * the OpenNLP NER model; as a result, if the model extracts more than one entity type, then more than one
+ * <code>dest</code> field will be populated.
+ * </p>
+ *
+ * <p>If the resolved <code>dest</code> field already exists in the document, then the
+ * named entities extracted from the <code>source</code> fields will be added to it.
+ * </p>
+ * <p>
+ * In the example below:
+ * </p>
+ * <ul>
+ *   <li>Named entities will be extracted from the <code>text</code> field and added
+ *       to the <code>names_ss</code> field</li>
+ *   <li>Named entities will be extracted from both the <code>title</code> and
+ *       <code>subtitle</code> fields and added into the <code>titular_people</code> field</li>
+ *   <li>Named entities will be extracted from any field with a name ending in <code>_txt</code>
+ *       -- except for <code>notes_txt</code> -- and added into the <code>people_ss</code> field</li>
+ *   <li>Named entities will be extracted from any field with a name beginning with "desc" and
+ *       ending in "s" (e.g. "descs" and "descriptions") and added to a field prefixed with "key_",
+ *       not ending in "s", and suffixed with "_people". (e.g. "key_desc_people" or
+ *       "key_description_people")</li>
+ *   <li>Named entities will be extracted from the <code>summary</code> field and added
+ *       to the <code>summary_person_ss</code> field, assuming that the modelFile only extracts
+ *       entities of type "person".</li>
+ * </ul>

+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

 == Type Token Filter
 
 This filter blacklists or whitelists a specified list of token types, assuming the tokens have type metadata associated with them. For example, the <<tokenizers.adoc#uax29-url-email-tokenizer,UAX29 URL Email Tokenizer>> emits "<URL>" and "<EMAIL>" typed tokens, as well as other types. This filter would allow you to pull out only e-mail addresses from text as tokens, if you wish.

+== OpenNLP Integration
+
+The `lucene/analysis/opennlp` module provides OpenNLP integration via several analysis components: a tokenizer, a part-of-speech tagging filter, a phrase chunking filter, and a lemmatization filter.  In addition to these analysis components, Solr also provides an update request processor to extract named entities - see <<update-request-processors.adoc#update-processor-factories-that-can-be-loaded-as-plugins,Update Processor Factories That Can Be Loaded as Plugins>>.
+
+NOTE: The <<OpenNLP Tokenizer>> must be used with all other OpenNLP analysis components, for two reasons: first, the OpenNLP Tokenizer detects and marks the sentence boundaries required by all the OpenNLP filters; and second, since the pre-trained OpenNLP models used by these filters were trained using the corresponding language-specific sentence-detection/tokenization models, the same tokenization, using the same models, must be used at runtime for optimal performance.
+
+See `solr/contrib/analysis-extras/README.txt` for information on which jars you need to add to your `SOLR_HOME/lib`.
+
+=== OpenNLP Tokenizer
+
+The OpenNLP Tokenizer takes two language-specific binary model files as parameters: a sentence detector model and a tokenizer model.  The last token in each sentence is flagged, so that following OpenNLP-based filters can use this information to apply operations to tokens one sentence at a time. See the http://opennlp.apache.org/models.html[OpenNLP website] for information on downloading pre-trained models.
+
+*Factory class:* `solr.OpenNLPTokenizerFactory`
+
+*Arguments:*
+
+`sentenceModel`:: (required) The path of a language-specific OpenNLP sentence detection model file. This path may be an absolute path, or path relative to the Solr config directory.
+
+`tokenizerModel`:: (required) The path of a language-specific OpenNLP tokenization model file. This path may be an absolute path, or path relative to the Solr config directory.
+
+*Example:*
+
+[source,xml]
+----
+<analyzer>
+  <tokenizer class="solr.OpenNLPTokenizerFactory"
+             sentenceModel="en-sent.bin"
+             tokenizerModel="en-tokenizer.bin"/>
+</analyzer>
+----
+
+=== OpenNLP Part-Of-Speech Filter
+
+This filter sets each token's type attribute to the part of speech (POS) assigned by the configured model. See the http://opennlp.apache.org/models.html[OpenNLP website] for information on downloading pre-trained models.
+
+NOTE: Lucene currently does not index token types, so if you want to keep this information, you have to preserve it either in a payload or as a synonym; see the examples below.
+
+*Factory class:* `solr.OpenNLPPOSFilterFactory`
+
+*Arguments:*
+
+`posTaggerModel`:: (required) The path of a language-specific OpenNLP POS tagger model file. This path may be an absolute path, or path relative to the Solr config directory.
+
+`filter class="solr.OpenNLPPOSFilterFactory" posTaggerModel="filename"
+
+*Examples:*
+
+The OpenNLP tokenizer will tokenize punctuation, which is useful for following token filters, but ordinarily you don't want to include punctuation in your index, so the `TypeTokenFilter` (<<filter-descriptions.adoc#type-token-filter,described here>>) is included in the examples below, with `stop.pos.txt` containing the following:
+

+
+=== OpenNLP Phrase Chunking Filter
+
+This filter sets each token's type attribute based on the output of an OpenNLP phrase chunking model.  The chunk labels replace the POS tags that previously were in each token's type attribute. See the http://opennlp.apache.org/models.html[OpenNLP website] for information on downloading pre-trained models.
+
+Prerequisite: the <<OpenNLP Tokenizer>> and the <<OpenNLP Part-Of-Speech Filter>> must precede this filter.
+
+NOTE: Lucene currently does not index token types, so if you want to keep this information, you have to preserve it either in a payload or as a synonym; see the examples below.
+
+*Factory class:* `solr.OpenNLPChunkerFilter`
+
+*Arguments:*
+
+`chunkerModel`:: (required) The path of a language-specific OpenNLP phrase chunker model file. This path may be an absolute path, or path relative to the Solr config directory.
+
+*Examples*:
+
+Index the phrase chunk label for each token as a payload:
+
+[source,xml]
+----
+<analyzer>
+  <tokenizer class="solr.OpenNLPTokenizerFactory"
+             sentenceModel="en-sent.bin"

+  <filter class="solr.OpenNLPChunkerFactory" chunkerModel="en-chunker.bin"/>
+  <filter class="solr.TypeAsPayloadFilterFactory"/>
+</analyzer>
+----
+
+Index the phrase chunk label for each token as a synonym, after prefixing it with "#" (see the <<filter-descriptions.adoc#type-as-synonym-filter,TypeAsSynonymFilter description>>):
+

+  <filter class="solr.OpenNLPChunkerFactory" chunkerModel="en-chunker.bin"/>
+  <filter class="solr.TypeAsSynonymFilterFactory" prefix="#"/>
+</analyzer>
+----
+
+=== OpenNLP Lemmatizer Filter
+
+This filter replaces the text of each token with its lemma. Both a dictionary-based lemmatizer and a model-based lemmatizer are supported. If both are configured, the dictionary-based lemmatizer is tried first, and then the model-based lemmatizer is consulted for out-of-vocabulary tokens. See the http://opennlp.apache.org/models.html[OpenNLP website] for information on downloading pre-trained models.
+
+*Factory class:* `solr.OpenNLPLemmatizerFilter`
+
+*Arguments:*
+
+Either `dictionary` or `lemmatizerModel` must be provided, and both may be provided - see the examples below:
+
+`dictionary`:: (optional) The path of a lemmatization dictionary file. This path may be an absolute path, or path relative to the Solr config directory. The dictionary file must be encoded as UTF-8, with one entry per line, in the form `word[tab]lemma[tab]part-of-speech`, e.g. `wrote[tab]write[tab]VBD`.
+
+`lemmatizerModel`:: (optional) The path of a language-specific OpenNLP lemmatizer model file. This path may be an absolute path, or path relative to the Solr config directory.
+
+*Examples:*
+
+Perform dictionary-based lemmatization, and fall back to model-based lemmatization for out-of-vocabulary tokens (see the <<OpenNLP Part-Of-Speech Filter>> section above for information about using `TypeTokenFilter` to avoid indexing punctuation):
+
+[source,xml]
