Abstract: Social networks contain complex structural information and rich semantic information. The research of multi-type data of interconnection and the behavioral relationship security of entity objects are facing great challenges. Knowledge graph is designed to process user data knowledge and behavior information, and to find the complex relationship between things, concepts and entity objects, so that the relationship between things can be clearly explained. Firstly, basic knowledge of knowledge graph was introduced. Secondly, based on knowledge graph, the behavioral relationship of users is visualized in the social network, and the key technologies and research progress of the three modules of behavioral knowledge extraction, behavioral knowledge expression, and behavioral knowledge processing are summarized. By experimental analysis and comparison of the technical models, the visual identification technology was introduced. By using probability soft logic to identify candidate behavioral knowledge, the accuracy of user behavior relationship visualization was improved. Finally, the application of user behavior relation visualization in user information retrieval, user security evaluation and behavior correlation analysis is introduced, the challenges of current research are discussed and analyzed, and its development is prospected.

Key words: knowledge graph, visualization, social network, user behavior
