The Natural Language Toolkit (NLTK) is a leading platform for building
Python programs to work with human language data. It provides easy-to-use
interfaces to over 50 corpora and lexical resources such as WordNet,
along with a suite of text processing libraries for classification,
tokenization, stemming, tagging, parsing, and semantic reasoning.
This package contains the modules for Python2.
