Why we included this project

NLTK is the classic Python toolkit for natural language processing, and it remains a staple of NLP teaching and research. It provides tokenizers, stemmers, part-of-speech taggers, parsers, and classifiers through one consistent API, along with dozens of built-in corpora and lexical resources such as WordNet. That makes it a good place to prototype text-processing pipelines before moving to heavier deep-learning stacks, and a solid way to understand how the core components of NLP work. Students and researchers get a self-contained environment for experiments and coursework, while developers can add standard NLP capabilities to Python applications without pulling in a large model runtime.
