题  目:Advanced Reasoning Services for Ontologies and Knowledge Graphs

内容简介:Ontology-like knowledge bases (KBs) have become a promising modelling tool in a wide variety of applications such as intelligent Web search, question understanding, in-context advertising, social media mining, and biomedicine. Such KBs are distinct from traditional KBs in that they are based on ontologies (as schemas) that assist in organization and access of information on the Web and from other sources. However, practical ontology-like KBs are usually associated with data of large volume, dynamic with content, and updated rapidly. Efficient systems have been developed for standard reasoning and query answering for OWL/Description Logic (DL) ontologies. In recent years, the issue of facilitating advanced reasoning services is receiving extensive attention in the research community. In this talk, we will discuss recent research results and challenges of three important reasoning tasks of ontologies including ontology change, query explanation and rule-based reasoning for OWL/DL ontologies.

报告人:Prof. Kewen Wang, Griffith University

报告人简介: Kewen Wang is a professor in the School of Information and Communication Technology at Griffith University, Australia. He was awarded a PhD in Theoretical Computer Science at Nankai University, China. Before he moved to Australia, he was an associate professor in the Department of Computer Science and Engineering at Tsinghua University in China for three years, a research sciencist in the Institute of Informatics at the University of Potsdam for two years as well as some other academic positions. His research interest is in Knowledge Representation and its applications (specifically, answer set programming and description logics). He has been publishing in the foremost conferences and journals in his area. He is regularly a (senior) member of program committee of major conferences in AI such as AAAI. IJCAI, KR, LPNMR, ISWC and ESWC. He is also a member of the editorial board of the Journal of Web Semantics. Further details of his
