PROBLEM TO BE SOLVED: To make it possible to clarify relevance that does not explicitly appear in texts and relevance that is difficult to be found by people.SOLUTION: The present invention relates to a technique of searching for relevant nodes. The technique comprises: in response to selection of a first node, displaying, as first relevant nodes, nodes having a first relevance of a predetermined value or more among nodes connected from the first node by two hops; and in response to selection of at least one of the first relevant nodes, displaying the selected first relevant node as a second node involving the first node. The technique may further comprise displaying, as second relevant nodes, nodes having a second relevance of a predetermined value or more among nodes connected from the second node by two hops. |
