| 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. | |
