NLTK Tutorial: What is NLTK Library in Python?

What is Natural Language Processing (NLP)?

Natural Language Processing (NLP) is a process of manipulating or understanding the text or speech by any software or machine. An analogy is that humans interact and understand each otherโ€™s views and respond with the appropriate answer. In NLP, this interaction, understanding, and response are made by a computer instead of a human.

What is NLTK?

NLTK (Natural Language Toolkit) Library is a suite that contains libraries and programs for statistical language processing. It is one of the most powerful NLP libraries, which contains packages to make machines understand human language and reply to it with an appropriate response.
