NLTK Stemmers
Interfaces used to remove morphological affixes from words, leaving
only the word stem. Stemming algorithms aim to remove those affixes
required for eg. grammatical role, tense, derivational morphology
leaving only the stem of the word. This is a difficult problem due to
irregular words (eg. common verbs in English), complicated
morphological rules, and part-of-speech and sense ambiguities
(eg. ``ceil-`` is not the stem of ``ceiling``).
StemmerI defines a standard interface for stemmers.
