Abstract
A structured document retrieval apparatus which fetches an objective document from many documents stored in a storage device. In the apparatus, a logical structure extraction unit extracts the logical structure, document attribute, and content of a structured document, and the extracted information is stored in a document information storage unit. Since the information is stored only in this unit, it is not necessary to conduct cumbersome duplicate management such that the matching of information is always maintained. In the retrieval, a logical structure decision unit checks a document to decide whether it has the same logical structure as that written in a retrieval expression or not. Only in a document having the same logical structure, a component (for example, author) which is the ultimate retrieval object of the document is first accessed to be retrieved.
