Subject [jira] [Commented] (MAHOUT-415) Lucene filter for Collocations
Date Fri, 20 May 2011 22:18:47 GMT


Ted Dunning commented on MAHOUT-415:

This is a very nice capability and given that it is done by Drew, it is likely good code.

Should we commit this or pass it over to Lucene?

> Collocations generated using Mahout could be used to form a whitelist of terms to index
into a Lucene index. This patch will provide a way to generate a serialized BloomFilter from
CollocationsOutput and a Lucene filter that will take a BloomFilter and emit tokens that are
members of that filter. This would allow a set of interesting collocations to be pre-computed
for a corpus and then allow the documents to be indexed using only those collocations.
