PROBLEM TO BE SOLVED: To provide a structured document management system for generating an appropriate value-index to perform high-speed retrieval concerning a plurality of structured documents with a schema not defined therein. SOLUTION: A structured document storage part 22 stores the plurality of structured documents. A structure information storage part 21 integrates structure elements included in structure information which are extracted from the documents, and stores them. A value-index generation processing part 3 determines at every structure element an index type, which indicates how held position information is arranged, based on the feature of the value of the structure element, concerning the value-index which holds the value of the structure element, the structured document including the value, and the position information for identifying the structure element. The part 3 generates the value-index, where arrangement indicated by the index type which is determined by an index type determining means is performed, at every structure. In the generation, designation by a user is not required or reduced. Application is performed even to an unfixed part so as to dispense with the analysis of a retrieval request.
