CAUSE ESTIMATION METHOD AND INFORMATION PROCESSING APPARATUS

Abstract

An information processing apparatus selects, out of nodes in a knowledge graph, a first node that is similar to a first phenomenon whose cause is to be estimated. The information processing apparatus generates a sub-knowledge graph including the first node and a second node by tracing from the first node as a starting point to the second node at an end on a cause side of a causal relationship. The information processing apparatus determines a confidence level of the sub-knowledge graph based on a similarity of a first node included in the sub-knowledge graph to a first phenomenon. The information processing apparatus then determines whether to include a third phenomenon indicated by the second node in the sub-knowledge graph in cause candidates of the first phenomenon based on the confidence level of the sub-knowledge graph.
