PROBLEM TO BE SOLVED: To provide an extended query graph pattern generation device and method and a program for generation for automatically extending an initial query graph pattern input by a user into a query graph pattern to be acquired by adding information relevant to a user when retrieving information with which a query graph pattern is matched from among a large amount of data having a graph structure.;SOLUTION: An extended query graph pattern generation device is configured to acquire an initial subgraph matched with an input initial query graph pattern from a graph structure database 13, and to acquire nodes in context data 14 matched with the nodes of the initial subgraph and property and nodes connected to those nodes from a graph structure database 13. The acquired nodes and property which do not exist in the initial subgraph, but exist in the context database 14 are added to the initial query graph pattern, so that an extended query graph pattern for retrieving the data added with information relevant to a user is generated.;COPYRIGHT: (C)2007,JPO&INPIT
