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". + +PyStemmer provides algorithms for several (mainly european) languages, by +wrapping the libstemmer library from the Snowball project in a Python module. + +It also provides access to the classic Porter stemming algorithm for english: +although this has been superceded by an improved algorithm, the original +algorithm may be of interest to information retrieval researchers wishing +to reproduce results of earlier experiments. |
