Overview of the CCKS 2019 Knowledge Graph Evaluation Track: Entity, Relation, Event and QA
This is an incremental overview paper that reviews existing tasks and methods from a specific conference track, aimed at researchers and practitioners in knowledge graph domains.
The paper provides an overview of the CCKS 2019 evaluation track, which included 6 tasks on knowledge graphs (entity, relation, event, and QA) and attracted over 1,600 teams, summarizing task definitions, methods, resources, strategies, and challenges to serve as a reference for future research and applications.
Knowledge graph models world knowledge as concepts, entities, and the relationships between them, which has been widely used in many real-world tasks. CCKS 2019 held an evaluation track with 6 tasks and attracted more than 1,600 teams. In this paper, we give an overview of the knowledge graph evaluation tract at CCKS 2019. By reviewing the task definition, successful methods, useful resources, good strategies and research challenges associated with each task in CCKS 2019, this paper can provide a helpful reference for developing knowledge graph applications and conducting future knowledge graph researches.
