Third Exabyte Informatics Symposium

The third Exaybe Informatics symposium took place on Tuesday, 14th November 2006, 5-6pm, in Room 1.11, Merchant Venturers Building, Woodland Road.

The speaker was Professor Georg Gottlob from Oxford University who spoke about "The Lixto Project: A Status Report"

ABSTRACT: We give an overview of the Lixto project, which is both a research project in database theory and a commercial enterprise that develops Web data extraction (wrapping) and Web service definition software. After reviewing the project's main motivations and ideas, in particular the use of a logic-based framework for wrapping, we give a short demo of some of the main features of the system and discuss a number of industry projects carried out by the Lixto Software corporation (www.lixto.com). Based on the project experience, we define goals and research directions for exploring new frontiers of Web data extraction, which will be discussed at the end of the talk.

Georg Gottlob is Professor of Computing Science and Fellow of St. Anne's College at Oxford University. Prior to that, he was Professor of Computer Science at Vienna University of Technology, Austria (1988-2005). His research interests are database theory (in particular, query languages), Web information processing, constraint satisfaction problems, nonmonotonic reasoning, finite model theory, and computational complexity. On the more applied side, he supervised a number of industry projects dealing with expert systems and with multimedia information systems. From 1989 to 1996 he directed the industry-funded Christian Doppler Laboratory for Expert Systems. He is a co-founder of Lixto Corporation, which provides solutions for automatically accessing, transforming, and syndicating data from the Deep Web. Lixto has been conceived to support and extend the vision of the "semantic web" as outlined by Tim Berners Lee -- to make it much easier for computers and humans to access, understand, and further process web content.

Gottlob got his Engineer and Ph.D. degrees in Computer Science from TU Vienna, Austria in 1979 and 1981, respectively. He was affiliated with the Italian National Research Council in Genoa, Italy, and with the Politecnico di Milano, Italy. During the spring semester of 1999 he was invited McKay Professor at UC Berkeley. Professor Gottlob was an invited speaker at many international conferences. He has received the Wittgenstein Award from the Austrian National Science Fund, is a Fellow of the European Coordination Committee for Artificial Intelligence, and a full member of the Austrian Academy of Sciences. He chaired the Program Committees of the 2003 International Joint Conference on Artificial Intelligence, and the 2000 ACM conference on Principles of Database Systems. He was editor-in-chief of Artificial Intelligence Communications (1997-2004), and is on the editorial boards of Journal of Computer and System Sciences, Artificial Intelligence, Informatica, Web Intelligence and Agent Systems, Journal of Applied Logic, and Journal of Discrete Algorithms.
