Passage Retrieval

Passage Retrieval is a specialized information retrieval technique in the field of natural language processing, aimed at extracting specific paragraphs or text snippets relevant to a query from a large number of documents, rather than returning entire documents. This technology improves the efficiency of users obtaining the content they need by accurately pinpointing information, and it is widely applied in search engines, question-answering systems, and information extraction scenarios, making it of significant practical value.
