I run OpenNLP's SentenceDetector command line too on the example text given at http://incubator.apache.org/opennlp/documentation/manual/opennlp.html#tools.sentdetect.detection
But, it doesnt give the correct output mentioned at that same link, instead it gives this output: Pierre Vinken, 61 years old, will join the board as a nonexecutive director Nov. 29. Mr. Vinken is chairman of Elsevier N.V., the Dutch publishing group. Rudolph Agnew, 55 years old and former chairman of Consolidated Gold Fields PLC, was named a director of this British industrial conglomerate. It created 5 sentences instead of 3. I tried using the Java API of SentenceDetector, and that too gives incorrect output. A friend of mine ran the command line tool and used the Java API in Windows, and it worked for him. Hence, I am guessing this could be a Linux specific problem. Thanks Chandra
