Abstract:

The RDF (Resource Description Framework) data model is proposed for modeling Web objects as part of developing the semantic web. It has been used in various applications. In this talk, I will review some classical RDBMS-based data management techniques. Then, I will discuss the large-scale RDF data management problem from the graph database perspective. Specifically, I will discuss how to use Subgraph Matching (SM) algorithms to process queries over RDF knowledge graphs. I will talk about two kinds of queries, one of which is SPARQL query and the other one is natural language question. Finally, I will demonstrate our graph-based RDF data managementsystem, called gStore.

 

Short Bio:

Lei Zou received his BS degree and Ph.D. degree in Computer Science at Huazhong University of Science and Technology (HUST) in 2003 and 2009, respectively. He joined Institute of Computer Science and Technology (ICST) of Peking University (PKU) since September 2009 as a faculty member. Now, he is an associate professor in ICST of PKU. Before joining PKU, he visited Hong Kong University of Science and Technology (HKUST) and University of Waterloo (UW). Hisrecent research interests include graph databases, RDF knowledge graph, particularly in graph-based RDF data management. So far, he has published more than 30 papers, including papers published in reputed journals and major international conferences, such as SIGMOD, VLDB, ICDE,EMNLP, TKDE, VLDB Journal.
