  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.
