Natural Language Processing

Definition

Natural Language Processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and humans through natural language. It involves the ability of machines to understand, interpret, and generate human language in a way that is both meaningful and useful. NLP combines computational linguistics with machine learning, allowing systems to process and analyze vast amounts of natural language data.
