Abstract: A data analyzing apparatus is provided with: a first weight memory unit for storing a weight assigned to a node or an edge in a directed graph; a second weight memory unit for storing a weight different from the weight stored in the first weight memory unit when the different weight is assigned to a combination of specific two or more edges, a combination of three or more nodes, or a combination of two nodes not in a series; a directed graph modification unit for duplicating, among nodes included in a target path that includes all nodes or edges included in the combination, a node for which there is a path, other than the target path, that leads to the node and for modifying the directed graph so that a node for which the path leading to the node is included in the target path is distinguished from a node for which the path is not included in the target path; and an evaluation unit for evaluating, based on the weight, a path leading from a first node to a second node in the modified directed graph.

Abstract: When an input acknowledging unit acknowledges the input of pre-conversion data from the user via the user interface, an ordinary conversion processing unit that uses a dictionary database displays a candidate of converted data. When the input of search data is acknowledged from the user via the user interface, a search conversion processing unit that uses a search service etc. displays search result data or the candidate of converted data.
