Patent ID: 7069505

Claim:
A document management system for managing tagged document data corresponding to a categorizing map, comprising: an inputting unit for inputting the tagged document data; a storing unit for storing document data which has been input by the inputting unit; a data processing unit for executing a data process under the control of a program; and a displaying unit for displaying document data stored in the storing unit, wherein the data processing unit comprises: document registering means for registering tagged document data, which has been input by the inputting unit, with the storing unit; document search index creating means for analyzing the document data registered by the document registering means and creating a search index which allows the document data to be searched for based on each tag; categorizing map creating means for creating a categorizing map having leaves having tagged contents of document data whenever a predetermined amount of document data is registered with the storing unit by the document registering means, wherein when a tag path is assigned as the development condition to an initial document set registered with the storing unit by the document registering means, the categorizing map creating means is operated: to select a first document from the initial document set and obtain a value of a tag path of the selected document; to extract a document set which does not contain the value of the tag path of the selected document from the initial document set; to treat the extracted document set as a new initial document set, select a first document from the new initial document set, and obtain the value of the tag path of the selected document; to extract a document set which does not contain the obtained tag path from the new initial document set; and to continue the process until the initial document set becomes null.
