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 It also provides access to the classic Porter stemming algorithm +for english: although this has been superceded by an improved algorithm, +the original algorithm may be of interest to information retrieval +researchers wishing to reproduce results of earlier experiments. + +WWW: http://pypi.python.org/pypi/PyStemmer/ |
