[jira] [Comment Edited] (LUCENE-4345) Create a Classification module

[ https://issues.apache.org/jira/browse/LUCENE-4345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13456053#comment-13456053 ]

I recently did some related research in text analysis and found that limiting terms to nouns&verbs was a 10-15% increase in all variations of the test.

So, filtering terms from Parts-of-Speech annotation will be very helpful. In my OpenNLP patch is a FilterPayloadsFilter which keeps or rips out terms based on a list of text payloads.

> Key: LUCENE-4345
> URL: https://issues.apache.org/jira/browse/LUCENE-4345
> Project: Lucene - Core
> Issue Type: New Feature
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
> Priority: Minor
> Attachments: LUCENE-4345_2.patch, LUCENE-4345.patch, SOLR-3700_2.patch, SOLR-3700.patch

> Lucene/Solr can host huge sets of documents containing lots of information in fields so that these can be used as training examples (w/ features) in order to very quickly create classifiers algorithms to use on new documents and / or to provide an additional service.
> So the idea is to create a contrib module (called 'classification') to host a ClassificationComponent that will use already seen data (the indexed documents / fields) to classify new documents / text fragments.
> The first version will contain a (simplistic) Lucene based Naive Bayes classifier but more implementations should be added in the future.
