<P>PROBLEM TO BE SOLVED: To enable a search according to patterns of past searches of individual users, in the search in a graph where a data element is a node and a relation between the data elements is a link. <P>SOLUTION: In an initial search, a reference node and a search condition are accepted from a user, a subgraph satisfying the search condition is searched for, and a route connecting the subgraph to the reference node is presented, for each subgraph being a search result. When the user selects a desired route from the multiple presented routes, the selected route is added to search route history data 10b, as a history route, in association with an ID of the user. When the user specifies a node of interest and instructs a history search, a history using search processing part 54 searches for a route identical to or similar to the history route of the user in the search route history data 10b, among routes extending from the node of the interest on the graph, and presents the route. <P>COPYRIGHT: (C)2013,JPO&INPIT |
