Abstract: An analysis condition for security risk for a data flow in a system to be analyzed is automatically generated. An analysis condition generating apparatus lA generates from a natural sentence, using ontology in which a relationship is described between one or more nodes on a data flow graph that indicates a data flow in a system to be analyzed and one or more edges that indicate an event related to the nodes, graph structural data indicating the relationship between the nodes and the edges, and generates an analysis condition for analyzing security risk for the system to be analyzed based on the graph structural data.
