Stemming algorithms
|
|
|
|
PyStemmer 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".
|
|
|
|
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although this has been superceded by an improved algorithm, the original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.
