Package nltk :: Module detect

Module detect

Functions for detecting a token's features. Features are stored in a dictionary which maps feature names to feature values.

(Not yet ported from NLTK: A feature encoder can then be used to translate the feature dictionary into a homogenous representation (such as a sparse boolean list), suitable for use with other processing tasks.)
