Time: 12pm-1pm, Wednesday, August 4 Place: Room A135 (BLENDER Lab), Science Building, Queens College/CUNY Speaker: Dr. Javier Artiles (CUNY) Title: Web People Search Abstract: In this talk I will present the problem of name ambiguity while searching for people on the Web. At the beginning of our work, in 2004, there were very few research papers on this topic, and no commercial web search engine would provide this type of facility. For this reason, our research methodology initially focused on the design and organisation (together with Prof. Sekine from New York University) of a competitive evaluation campaign for Web People Search systems. Once the campaign had been run for two years, we used the standard test suites built to perform our own empirical studies on the nature and challenges of the task. The evaluation campaign, WePS, was organized in 2007 (as a SemEval 2007 task) and in 2009 (as a WWW 2009 workshop). WePS was crucial in the process to lay the foundations of a proper scientific study of the Web People Search problem. A third WePS campaign is under way (as a CLEF lab). WePS-3 has added new features to previous tasks as well as a new entity disambiguation task based on Twitter data. Speaker's Bio: Javier Artiles received his PhD in Computer Science from the UNED University in 2009 under the direction of Prof. Julio Gonzalo and Enrique Amigo. His research interests lie in natural language processing, especially information extraction and information retrieval. His current research is focused on Web People Search (WePS), document clustering and personal attribute extraction from web documents.
