Subject [jira] [Commented] (LUCENE-2899) Add OpenNLP Analysis capabilities as a module
Date Fri, 01 Feb 2013 08:25:15 GMT


Kai Gülzau commented on LUCENE-2899:

I have applied the Patch to trunk, modified the build scripts manually (ignoring javadoc tasks)
and built the opennlp jars.
Jars are running in a vanilla Solr 4.1 environment.

- solr_server4.1\solr\lib\opennlp\
-- jwnl-1.4_rc3.jar
-- lucene-analyzers-opennlp-5.0-SNAPSHOT.jar (build with patch)
-- opennlp-maxent-3.0.2-incubating.jar
-- opennlp-tools-1.5.2-incubating.jar
-- solr-opennlp-5.0-SNAPSHOT.jar (build with patch)

with <lib dir="../lib/opennlp" /> in solrconfig.xml

Works for me:

> 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
