Brief Summary of the talk:
The Web is saturated with data that can enrich applications in areas such as e-commerce, health, and finance. But web-based information is hard to acquire, hard to understand, and hard to integrate into applications -- particularly compared to traditional structured data. This talk will give an overview of the challenges in understanding, integrating, and exploiting web data, and then discuss some of the activities within Oxford University's Information Systems group that tackle these problems.
As an example, we will go into detail on one particular project, RoseAnn, which extracts semantics from text and HTML documents on the Web, performing integration of the diverse opinions of many individual semantic annotators.  I will explain the background assumptions behind this kind of "annotation aggregation", present the RoseAnn solution, and discuss our experience with the prototype.
The talk includes joint work with Luying Chen, Tim Furche, Giorgio Orsi, and Stefano Ortona.  Some of the work is or will be presented at VLDB 2013 and VLDB 2014.
Short Biography of the speaker:
Michael Benedikt is a professor at Oxford University's Computer Science department, and a fellow of University College Oxford. He came to Oxford after a decade in US industrial research laboratories, including a position as Distinguished Member of Technical Staff at Bell Laboratories. He has worked extensively in mathematical logic, finite model theory, verification, database theory, and database systems, and has served as chair of the ACM's main database theory conference, Principles of Database Systems. The current focus of his research is Web data management, with recent projects including querying of the deep Web, querying and integration of annotated data, and querying of web services.
