Abstract:

An early vision in Computer Science was to create intelligent systems capable of reasoning on large amounts of data. Independent results in the areas of Description Logic and Relational Databases have advanced us towards this vision. Description Logic research has advanced the understanding of the tradeoff between the computational complexity of reasoning and the expressiveness of logic languages; and now underpins the Semantic Web. Database research has advanced the theory and practice of storage and management of data, embodying features such as views and recursion, which are capable of representing reasoning. Despite the independent advances, the interface between Relational Databases and Semantic Web is poorly understood.

My research revisits this vision with respect to current technology and addresses the following question: How and to what extent can Relational Databases be integrated with the Semantic Web? The thesis is that much of the existing Relational Database infrastructure can be reused to support the Semantic Web.

In this talk, I will discuss how a Relational Database can be automatically virtualized as a Semantic Web data source and how can a Relational Database be mapped to existing Semantic Web ontologies and act as a reasoner. I will conclude with a discussion on the extent that Relational Databases can integrated with the Semantic Web and open problems.

Bio:

Juan F. Sequeda is the co-founder of Capsenta, a spin-off from his research, and the Senior Director of Capsenta Labs. He holds a PhD in Computer Science from the University of Texas at Austin.? His research interests are on the intersection of Logic and Data and in particular between the Semantic Web and Relational Databases for Data Integration. He is the developer of Ultrawrap a patented system that virtualizes Relational Databases as Semantic Web data sources, which has spun-off into Capsenta. Juan was a recipient of the NSF Graduate Research Fellowship, Best Student Research Paper at the 2014 International Semantic Web Conference, and received 2nd Place in the 2013 Semantic Web Challenge for his work on ConstituteProject.org. Juan is currently on the Editorial Board of the Journal of Web Semantics, member of multiple program committees (ISWC, ESWC, WWW, AAAI, IJCAI) and has been an invited expert member and standards editor at the World Wide Web Consortium (W3C). He is also the co-creator of the Consuming Linked Data Workshop series.
