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for english: although this has been superceded by an improved algorithm,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.
