SWISH::Stemmer Description

Stemmer is a Perl extension for stemming words using a modified version of the Stem routine from the SWISH search engine. Stemmer is a Perl extension for stemming words using a modified version of the Stem routine from the SWISH search engine.This module provides access to the Stem() function used in SWISH-E to stem words. This module is needed if you wish to highlight words in source documents.Not that this module includes the stemmer.c function from the SWISH-E distribution. You should make sure that the stemmer.c file contained here is closely matched to the stemmer.c module in the SWISH-E distribution.Also, there is a SWISH-E library that will contain the Stem() and SwishStem() functions. So you may be able to access that library instead of using this module. Check the SWISH-E discussion list for more info. Purpose: Implementation of the Porter stemming algorithm documented in: Porter, M.F., "An Algorithm For Suffix Stripping," Program 14 (3), July 1980, pp. 130-137. Provenance: Written by B. Frakes and C. Cox, 1986. Changed by C. Fox, 1990. - made measure function a DFA - restructured structs - renamed functions and variables - restricted function and variable scopes Changed by C. Fox, July, 1991. - added ANSI C declarations - branch tested to 90% coverage Notes: This code will make little sense without the the Porter article. The stemming function converts its input to lower case. Requirements: · Perl
