Title:
INFERRING DEVICE, INFERRING METHOD, AND INFERRING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/124502
Kind Code:
A1
Abstract:
An inferring device (10) includes an information linking unit (14) which generates integrated information by linking, in a forward chain, information belonging to mutually different domains, from among dynamically varying external information, using knowledge information provided from a knowledge base (11a), and inference rules provided from a rule database (12a), and an information analyzing unit (15), wherein: the information belonging to mutually different domains is information that can be represented as a directed graph having nodes and edges; the integrated information is an integrated graph generated by combining directed graphs, which constitute the information belonging to different domains; and the information analyzing unit (15) calculates the importance of the nodes, which are constituent elements of the integrated graph, using the probability of reaching each node when a random walk on the integrated graph has converged to a steady state, or using the PageRank algorithm, and relationship data indicating the degree of relationship between the nodes, provided from a relationship database (19a).
