Title: Broad Data: The Emerging Data Science Challenge on the Word Wide Web
Prof. Jim Hendler, Rennselaer Polytechnic Institute, USA
Date & Time: January 23, 2012 15:00
Venue: Lecture Hall, 03rd Floor, B Block, Dept. of Computer Science & Engg., Kanwal Rekhi Bldg.
"Big Data" is becoming an over-used phrase in the computing world. It has been used to refer to the very large datasets generated by scientists, to the many petabytes of data held by companies like Facebook and Google, and to analyzing real-time data assets like the stream of twitter messages emerging from events around the world. Key areas of interest include technologies to manage much larger datasets (cf. NoSQL), technologies for the visualization and analysis of databases, and datamining approaches. Recently, however, we have begun to see the emergence of another, and equally compelling data challenge -- that of the "Broad data" that emerges from the millions of raw datasets available on the World Wide Web. Performing analysis in this environment is a huge challenge. For broad data the new challenges that emerge include Web-scale data search and discovery, rapid and potentially ad hoc integration of datasets, visualization and analysis of only-partially modeled datasets, and issues relating to the policies for data use, reuse and combination. In this talk, we present the broad data challenge and discuss potential starting points for solutions. We illustrate these approaches using data from a "meta-catalog" of over 450,000 open government datasets that have been collected from hundreds of data catalogs from around the world.
Speaker Profile:
James Hendler is the Tetherless World Professor of Computer and Cognitive Science, and the Assistant Dean for Information Technology and Web Science, at Rensselaer. He is also a faculty affiliate of the Experimental Multimedia Performing Arts Center (EMPAC), serves as a Director of the UK's charitable Web Science Trust and is a visiting Professor at the Institute of Creative Technology at DeMontfort University in Leicester, UK. Hendler was the recipient of a 1995 Fulbright Foundation Fellowship, is a member of the US Air Force Science Advisory Board, and is a Fellow of the American Association for Artificial Intelligence, the British Computer Society and the IEEE. He is the Editor-in-Chief emeritus of IEEE Intelligent Systems and is the first computer scientist to serve on the Board of Reviewing Editors for Science. In 2010, Hendler was named one of the 20 most innovative professors in America by Playboy magazine and was selected as an 'Internet Web Expert" by the US government.
