The term "natural language processing" (NLP) encompasses the field of AI focused on the interaction between computers and humans through natural language. It involves the development of algorithms and models that enable machines to understand, interpret, and generate human language in a meaningful way. NLP applications include sentiment analysis, language translation, chatbots, and speech recognition. By bridging the communication gap between human language and machine interpretation, NLP facilitates enhanced user experiences and efficiencies across various applications and industries.
