Subject Stemmer implementations for Lucene
Date Wed, 23 Oct 2002 17:16:18 GMT
Hi -

I was curious what word stemmers are available for Lucene or (in 
general) available to the public. I see that Lucene includes:

    * Porter Stemmer (English)
    * Caumanns Stemmer (German)
    * Snowball Russian Stemmer (Porter-based)

I was specifically interested in the stemmer written by Bob Krovetz in 
his paper "Viewing Morphology as an Inference Process" (later 
incorporated into the InQuery project as "KSTEM"). Are there any others 
that people are aware of? Any that would be good candidates for 
inclusion in the Lucene project?

If algorithms were available, I would be more than happy to help make 
them Java/Lucene-friendly...
