Otis Gospodnetic commented on LUCENE-1910:
------------------------------------------
* I'll second Mark's suggestion to extract the Information Gain piece of the
patch into separate class(es), so we can reuse it in other places. It looks
like it's currently an integral part of MoreLikeThisUsingTags class. Would
that be possible?
* I noticed the code needs ASL (the Apache Software License) added.
* Also, could you please use the Lucene code format? (Eclipse/IntelliJ
templates are at the bottom of
http://wiki.apache.org/lucene-java/HowToContribute )

> Key: LUCENE-1910
> URL: https://issues.apache.org/jira/browse/LUCENE-1910
> Project: Lucene - Java
> Issue Type: New Feature
> Components: contrib/*
> Reporter: Thomas D'Silva
> Priority: Minor
> Attachments: LUCENE-1910.patch
>
>
> I would like to contribute a class based on the MoreLikeThis class in
> contrib/queries that generates a query based on the tags associated
> with a document. The class assumes that documents are tagged with a
> set of tags (which are stored in the index in a seperate Field). The
> class determines the top document terms associated with a given tag
> using the information gain metric.
> While generating a MoreLikeThis query for a document the tags
> associated with document are used to determine the terms in the query.
> This class is useful for finding similar documents to a document that
> does not have many relevant terms but was tagged.
