perl-Lingua-Stem

Stemming of words

This routine applies stemming algorithms to its parameters, returning the stemmed words as appropriate to the selected locale. You can import some or all of the class methods. use Lingua::Stem qw (stem clear_stem_cache stem_caching add_exceptions delete_exceptions get_exceptions set_locale get_locale :all :locale :exceptions :stem :caching); :all - imports stem add_exceptions delete_exceptions get_exceptions set_locale get_locale :stem - imports stem :caching - imports stem_caching clear_stem_cache :locale - imports set_locale get_locale :exceptions - imports add_exceptions delete_exceptions get_exceptions Currently supported locales are: DA - Danish DE - German EN - English (also EN-US and EN-UK) FR - French GL - Galician IT - Italian NO - Norwegian PT - Portuguese RU - Russian (also RU-RU and RU-RU.KOI8-R) SV - Swedish If you have the memory and lots of stemming to do, I *strongly* suggest using cache level 2 and processing lists in 'big chunks' (long lists) for best performance.
