NLTK (Natural Language Tool Kit) is a suite of Python libraries and 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, wrappers for industrial-strength NLP libraries, and an active discussion forum (refer NLTK Org).
NLTK has been pre-installed into COLAB. Developers just need to import the library whenever it is needed.
