Natural Language Processing (NLP)
Explanation level
Introduction
Natural Language Processing (NLP) is a branch of Artificial Intelligence. It gives computers the ability to understand text and spoken words the same way humans do. Writing AI-based NLP software is an extremely difficult task. The NLP software has to accurately understand the intended meaning of text or voice data for interaction between computers and humans. It is about making computers learn, process, and manipulate natural language just like the human brain.
