I spent some time earlier this year exploring various NLP engines (Freeling, OpenNLP, DELPH-IN, LingPipe, UIMA, and a few others). Of them, FreeLing (http://nlp.lsi.upc.edu/freeling/ http://nlp.lsi.upc.edu/freeling/) was far and away the technical leader for my needs: - Decent documentation - Relatively easy to compile and install - Working (and practical) example code - Easily configured - Extremely flexible design - Supports many written languages - Supports Java, C++, and has a simple client-server model - Good execution time (fast code) - Solid code base (no crashes in six months) See also: http://en.wikipedia.org/wiki/List_of_natural_language_processing_toolkits http://en.wikipedia.org/wiki/List_of_natural_language_proces...
