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 enables machines to understand, interpret, and respond to human language in a valuable way, bridging the gap between human communication and computer understanding. NLP combines computational linguistics, machine learning, and cognitive psychology to create systems that can process text and speech effectively.
