Title:

METHOD AND APPARATUS FOR MISSING LINK PREDICTION FOR KNOWLEDGE GRAPH

Document Type and Number:

WIPO Patent Application WO/2022/261840

Kind Code:

A1

Abstract:

A method, apparatus, system and computer-readable medium for missing link prediction for a knowledge graph are presented. A method (100) can include following steps: predicting (S101) at least one missing link in a first knowledge graph; for each missing link, measuring (S102) effect on the first knowledge graph by adding the missing link, displaying (S103) the measured effect to a user, receiving (S104) the user's decision on whether to add the missing link based on the measured effect, and processing (S105) the first knowledge graph according to the user's decision. With the solution provided, data quality of a knowledge graph can be improved.
