Subject [jira] [Commented] (LUCENE-2899) Add OpenNLP Analysis capabilities as a module
Date Fri, 01 Feb 2013 10:33:13 GMT


Joern Kottmann commented on LUCENE-2899:

The jwnl library is only needed if you use the OpenNLP Coreference component, otherwise its
safe to exclude it. The 1.4_rc3 version is not tested anyway and its likely that the Coreferencer
does not probably run with it.

> Now that OpenNLP is an ASF project and has a nice license, it would be nice to have a
submodule (under analysis) that exposed capabilities for it. Drew Farris, Tom Morton and I
have code that does:
> * Sentence Detection as a Tokenizer (could also be a TokenFilter, although it would have
to change slightly to buffer tokens)
> * NamedEntity recognition as a TokenFilter
> We are also planning a Tokenizer/TokenFilter that can put parts of speech as either payloads
(PartOfSpeechAttribute?) on a token or at the same position.
> I'd propose it go under:
> modules/analysis/opennlp
