Abstract:
An information retrieval apparatus for retrieving a hyper-document system composed of links between nodes, which are units of information, comprising:a node group constituting part that constitutes a node group comprising nodes, which are connected through links and are similar in contents with respect to nodes in said hyper-document system; a component node storing part that stores component nodes constituting said node group; an information retrieval part that retrieves, when a retrieval request is inputted, similar node groups having a high degree of similarity to said retrieval request among a plurality of said node groups; a similarity calculation part that calculates degrees of similarity between the component nodes stored in said component node storing part and said retrieval request with respect to said similar node groups returned as a candidate as a result of the retrieval by said information retrieval part; and a similarity retrieval result displaying part that displays paths for accessing each component node in said similar node groups in such a manner that component nodes having a high degree of similarity to said retrieval request can be distinguished.
