Abstract
In retrieval in which information having meaningful consistence is regarded as one unit, useful information within a hypertext structure retrieved is rendered capable of being effectively perused. A node group constituting part constitutes node groups to be retrieved on the basis of combination through links and the degree of similarity in contents from information in a hyper-document system. A component node storing part stores node group identification address information sent from the node group constituting part. When a retrieval request is given, an information retrieval part calculates the degree of similarity between the retrieval request and the node group. A similarity calculation part acquires the component nodes of a node group similar to the retrieval request from the component node storing part, and calculates the degrees of similarity between the component nodes acquired and the retrieval condition profile to rank the component nodes. A similarity retrieval result display part displays access paths to each component node in such a manner that component nodes having a high ordinal rank in the degree of similarity can be distinguished.
