Natural Language Processing (NLP)

Definition

Natural Language Processing (NLP) is a branch of artificial intelligence that focuses on the interaction between computers and human language, enabling machines to understand, interpret, and respond to human language in a valuable way. This involves the development of algorithms and models that help computers process and analyze large amounts of natural language data, facilitating tasks such as translation, sentiment analysis, and dialogue systems. NLP plays a vital role in improving how machines comprehend context and meaning in human communication.

5 Must Know Facts For Your Next Test
