Definition
In RAG pipelines and AI Agents, Named Entity Recognition (NER) is the automated extraction of specific identifiers—such as product names, dates, or proprietary codes—from queries or documents to enable precise metadata filtering and structured tool-calling. While it increases retrieval precision by narrowing search spaces, it introduces additional latency and computational overhead to the pre-processing stage.
In an AI context, NER isn't just for linguistic analysis; it serves as a bridge between unstructured natural language and structured database constraints.
