NLU definition

NLU definition refers to Natural Language Understanding, a branch of artificial intelligence that enables machines to comprehend, interpret, and extract meaning from human language in its natural form. This computational process goes beyond simple keyword matching to understand context, intent, entities, and semantic relationships within text or speech. NLU systems employ deep learning models, transformer architectures, and linguistic analysis to perform core tasks including intent classification, named entity recognition, slot filling, sentiment analysis, and semantic parsing. The technology combines syntactic analysis for grammatical structure with semantic analysis for meaning extraction, enabling machines to understand ambiguity, context dependencies, and implicit information. NLU serves as the foundation for conversational AI, chatbots, voice assistants, and automated text analysis systems. For AI agents, NLU provides essential language comprehension capabilities enabling natural human-computer interaction, instruction interpretation, and contextual reasoning.
