Machine learning has promoted the application of artificial intelligence (AI) techniques to a wide variety of social problems. Accordingly, being able to explain the reason for an AI decision is becoming important to ensure the secure and safe use of AI techniques. On this background, for example, the Knowledge Graph Reasoning Challenge (KGRC) has been organized since 2018*, **. It aims to promote techniques for explainable AI using knowledge graphs.
In this workshop, we would like to discuss a wider variety of knowledge graph reasoning technologies for explainable AI in various domains. Although one typical topic is to solve mystery stories in the KGRC, knowledge graphs and related technologies in other domains are also welcome.
