摘要

A graph summarizing device comprising: a calculation unit which, when a graph, with each node having a cause degree that indicates the degree of cause for the state of the graph and each side having a weight that indicates the strength of causal relationship between the nodes, changes, calculates, for each node of the graph after change, the degree of importance based on the cause degree of nodes of the graph before change; a selection unit for selecting a first node the importance degree of which is smaller than or equal to a threshold as a candidate to delete; and a deletion unit for deleting the first node, whereby the graph summarizing device realizes graph summarization with which it is possible to suppress a decrease in the accuracy of cause estimation by a causal graph.
