摘要

PROBLEM TO BE SOLVED: To provide a structured document management device for improving convenience in retrieval.SOLUTION: A structured document management device includes: a document storage part; a header extraction part; a relevancy calculation part; a document retrieval part; a header selection part; and a header display part. The document storage part stores a plurality of structured documents. The header extraction part extracts headers of the structured documents, and creates a header list including the extracted headers. The relevancy calculation part calculates relevancy of concepts between vocabulary in the structured documents and the headers corresponding to the structured documents, respectively. The document retrieval part retrieves a structured document including vocabulary matched to a keyword for retrieval. The header selection part selects a header with large relevancy to the vocabulary matched to the keyword for retrieval by giving priority over a header with small relevancy. The display control part displays the header selected by the header selection part on a display part as a display header.
