NLKT

NLKT is a Python-based set of tools and programs for symbolic and statistical natural language processing (NLP) in English. Graphical demonstrations and sample data are included in NLTK. NLTK is designed to aid education and research in natural language processing (NLP).

It also aids other closely allied fields such as empirical linguistics, cognitive science, artificial intelligence, information retrieval, and machine learning. NLTK has been effectively utilised as a teaching tool, a tool for individual study, and a platform for prototyping and developing research systems.
