Title: Towards Knowledge Graph Federations: Issues and Technologies
Time: 9:20-10:20 (Beijing time, UTC+8), September 20, 2020
Prof. Xiang Zhao, National University of Defense Technology
Abstract: In enterprises at scale, knowledge bases tend to be constructed by different departments along with the development of their own information systems, which hinders the use of knowledge at the enterprise level. To overcome the limit, on top of solitary knowledge graphs, we present the concept of knowledge graph federation with the aim of uniting knowledge graphs to boost intelligent services at the enterprise level. In this talk, we will discuss the notion of knowledge graph federation, as well as current issues in the direction. Particularly, relating to the issues, we will share some recent progress on constructing domain knowledge graphs from noisy Chinese text, and benchmarking the performance of knowledge graphs fusion via entity alignment.
