| Tokenizer | Persian specific tokenization code. In particular, it has a stemmer, The stemmer is a modified variant (handling prefixes slightly differently) of my stab at porting Nick Patch's Perl port, https://metacpan.org/pod/Lingua::Stem::UniNE::FA, of the stemming algorithm by Ljiljana Dolamic and Jacques Savoy of the University of Neuchâtel. The Java version of this is at http://members.unine.ch/jacques.savoy/clef/persianStemmerUnicode.txt (beware of Java's handling of Unicode). |
