Natural Language Processing

Definition

Natural language processing (NLP) is a field of artificial intelligence that focuses on the interaction between computers and human language, enabling machines to understand, interpret, and respond to text or spoken input in a way that is valuable. This technology bridges the gap between human communication and computer understanding, making it essential for collecting and analyzing data from various sources, like social media and surveys, to extract meaningful insights.
