METHOD AND DEVICE FOR COMPLETING KNOWLEDGE BY USING RELATION LEARNING BETWEEN QUERY AND KNOWLEDGE GRAPH

Document Type and Number:

WIPO Patent Application WO/2022/107989

Kind Code:

A1

Abstract:

Disclosed are a method and a device for completing knowledge by using relation learning between a query and a knowledge graph. According to the present invention, provided is a device for completing knowledge by using relation learning between a query and a knowledge graph, comprising: a query embedding module that outputs a query embedding value corresponding to an input query; a topic extraction module that extracts topics from the input query; a knowledge graph embedding module that outputs embedding values for a plurality of predicates, subjects, and objects included in the knowledge graph; a similarity calculation module that determines the predicate most similar to the query by calculating the similarity between the embedding value of the query and the embedding values of each of the plurality of predicates; an embedding connection module that connects the embedding value of the query with the embedding value of the most similar predicate; and a scoring module that infers a new triple by using the extracted topic, the embedding value connecting the query embedding value and the embedding value of the most similar predicate, and the subjects and objects of the knowledge graph.
