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 computers to understand, interpret, and respond to human language in a valuable way, facilitating seamless communication. This capability is vital for various applications, such as search systems that retrieve information based on user queries and voice interfaces that allow users to engage with technology using everyday speech.
