Snowball stemming algorithms for use in Information Retrieval Snowball
provides access to efficient algorithms for calculating a "stemmed"
form of a word. This is a form with most of the common morphological
endings removed; hopefully representing a common linguistic base form.
This is most useful in building search engines and information
retrieval software; for example, a search with stemming enabled should
be able to find a document containing "cycling" given the query
"cycles".
Snowball provides algorithms for several (mainly European) languages.
It also provides access to the classic Porter stemming algorithm for
English: although this has been superseded by an improved algorithm,
the original algorithm may be of interest to information retrieval
researchers wishing to reproduce results of earlier experiments.
