Natural Language Understanding

While NLP covers both understanding and generation of language, NLU specifically addresses the comprehension side. It involves parsing syntax, resolving ambiguity, understanding semantic relationships, and extracting structured meaning from unstructured text. In customer support, NLU is what allows an AI agent to determine that 'my thing broke after two days' refers to a product defect complaint requiring a warranty check, not a general inquiry.

Advanced NLU handles coreference resolution (understanding that 'it' refers to the product mentioned earlier), contextual interpretation (the same word meaning different things in different contexts), and pragmatic inference (understanding implied meaning beyond literal words). Strong NLU capabilities directly translate to higher automation rates and fewer misrouted tickets.
