Original email:

Hi all,

  I have ported the kstem stemmer to Java and incorporated it to 
Lucene. You can get the source code (Kstem.jar) from the following website:

http://ciir.cs.umass.edu/downloads/

  Just click on "KStem Java Implementation" (you will need to register 
your e-mail, for free of course, with the CIIR --Center for Intelligent 
Information Retrieval, UMass -- and get an access code).


Content of Kstem.jar:

java/org/apache/lucene/analysis/KStemData1.java
java/org/apache/lucene/analysis/KStemData2.java
java/org/apache/lucene/analysis/KStemData3.java
java/org/apache/lucene/analysis/KStemData4.java
java/org/apache/lucene/analysis/KStemData5.java
java/org/apache/lucene/analysis/KStemData6.java
java/org/apache/lucene/analysis/KStemData7.java
java/org/apache/lucene/analysis/KStemData8.java
java/org/apache/lucene/analysis/KStemFilter.java
java/org/apache/lucene/analysis/KStemmer.java

KStemData1.java, ..., KStemData8.java   Contain several lists of words 
used by Kstem
KStemmer.java      Implements the Kstem algorithm 
KStemFilter.java     Extends TokenFilter applying Kstem


To compile

unjar the file Kstem.jar to Lucene's "src" directory, and compile it 
there. 


What is Kstem?

  A stemmer designed by Bob Krovetz (for more information see 
http://ciir.cs.umass.edu/pubfiles/ir-35.pdf).
