STRUCTURED DOCUMENT MANAGEMENT DEVICE, STRUCTURED DOCUMENT SEARCH METHOD

摘要

A structured document management device according to an embodiment of the present invention is provided with a document storage unit, a heading extraction unit, a relevance computation unit, a document search unit, a heading selection unit and a heading display unit. The document storage unit stores multiple structured documents. The heading extraction unit extracts the headings of the structured documents, and creates a heading list that contains the extracted headings. The relevance computation unit computes a conceptual relevance between each of multiple words and multiple headings, said words being in the structured documents, said headings corresponding to the structured documents. The document search unit searches for a structured document that contains a word that matches a search keyword. The heading selection unit selects a heading, giving greater precedence to a heading with a large relevance to the word that matches the search keyword, than to a heading with a small relevance to said word. A display control unit displays the heading selected by the heading selection unit, said heading being displayed as a display heading on a display unit.
