What is NLTK?
NLTK, the Natural Language Toolkit, is a prominent platform designed for developing Python applications that process human language data. It provides accessible interfaces to numerous corpora and lexical resources, including WordNet. The toolkit features a collection of text processing libraries enabling tasks such as classification, tokenization, stemming, tagging, parsing, and semantic reasoning.
Additionally, NLTK includes wrappers for robust, industrial-strength NLP libraries. Accompanied by a practical guide that introduces programming concepts alongside computational linguistics topics and extensive API documentation, NLTK serves a diverse audience, including linguists, engineers, students, educators, researchers, and industry professionals. It is a free, open-source, community-driven project available for Windows, Mac OS X, and Linux.
