Dear Wiki user, You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.
The "OpenNLP" page has been changed by KojiSekiguchi: http://wiki.apache.org/solr/OpenNLP?action=diff&rev1=10&rev2=11 NLP is a large field of inquiry. Unless you are familiar with it you may find this patch confusing. The [[http://opennlp.apache.org/|Apache OpenNLP project]] is the best place to learn what this package can do. == Introduction == - OpenNLP is a toolkit for Natural Language Processing (NLP). It is an Apache top-level project located [[here|http://opennlp.apache.org/]]. It includes implementations of many popular NLP algorithms. This project integrates some of its features into Lucene and Solr. This first effort incorporates Analyzer chain tools for sentence detection, tokenization, Parts-of-Speech tagging (nouns, verbs, ejaculations, etc.), Chunking (noun phrases, verb phrases) and Named Entity Recognition. See the OpenNLP project page for information on the implementations. Here are some use cases: + OpenNLP is a toolkit for Natural Language Processing (NLP).

This would be useful for many free text applications. The FilterPayloadsFilter and StripPayloadsFilter below are required for this. See "Full Example" below.
