<P>PROBLEM TO BE SOLVED: To exclude redundant information and generate a simple tree structure when a tree structure with a simplified hyper text structure is generated. <P>SOLUTION: A tree structure generation part 1030 refers to link information among documents in a link table 1024, sequentially follows links between documents from a document of starting point, and incorporates documents of link destinations of the links, as the slaves of the documents of link origins of the links, into tree structure to generate tree structure information. In this process, when the tree structure generation part 1030 incorporates a second document which is the link destination of a first document, as the slave of the first document, into the tree structure, a redundancy link deletion part 1040 determines whether the second document is also the link destination of the master document of the first document in the tree structure based on the link table 1024. When determining that the second document is also the link destination of the master document, the redundancy link deletion part stops the incorporation of the second document, as the slave of the first document, into the tree structure. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
