Relevance analyzing device and method

Abstract

It becomes possible to implement a route search fast, and furthermore routes whose meanings are easy to understand are searched for by linking routes on the basis of relations with similar backgrounds. A provided relevance analyzing device includes a control section and a database. The database stores: node data about nodes on a network representing relevance between a plurality of events, and edge data about edges representing interrelationships between the events. The control section includes: an inter-edge background similarity computing section that computes a similarity between documents corresponding to two edges by using the node data and edge data stored in the database; and a route computing section that computes routes with high similarities as routes on the network.
