Report on the First International Knowledge Graph Reasoning Challenge 2023

Abstract

According to applying AI systems to a wide variety of social systems, the explanation for the AI decision is becoming important to guarantee the security and safety of such AI systems. Therefore, the Special Interest Group on Semantic Web and Ontology of JSAI started the Knowledge Graph Reasoning Challenge in 2018. It calls for techniques for reasoning and/or estimating criminals with a reasonable explanation based on knowledge graphs representing well-known stories of Sherlock Holmes. The challenges were held 4 times in Japan. Through them, 29 works were submitted in total. Based on these results and experience, we had the first International Knowledge Graph Reasoning Challenge 2023 (IKGRC2023). This paper describes a summary report of the IKGRC2023, and them works submitted it are overviewed.
