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English: although this has been superseded by an improved algorithm, the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.
.
This package contains the pure Python module that implements Snowball
algorithms. When python3-stemmer package (which contains the C extension)
is installed, it uses that extension instead of the pure Python code.
