Natural language processing (NLP) is a method computer programs can use to interpret human language. NLP is one type of artificial intelligence (AI). Modern NLP models are mostly built via machine learning, and also draw on the field of linguistics — the study of the meaning of language.

NLP enables computers and digital devices to recognize, understand and generate text and speech by combining computational linguistics—the rule-based modeling of human language—together with statistical modeling, machine learning (ML) and deep learning.
