Abstract
According an embodiment, an information processing device includes a memory and one or more processors coupled to the memory. The one or more processors are configured to: cluster key phrases extracted from a document group to generate clusters each including items; extract a sub-document group corresponding to a specified key phrase from the document group; calculate a score for each of the clusters, the score indicating usefulness of information displayed in a graph image that indicates an amount of information for each of the items in the sub-document group; select clusters to be displayed whose scores are from a highest ranking to a predetermined ranking, among the clusters; and generate the graph image of each of the clusters to be displayed.
