Integrated Access to Web Databases

Dr. Weiyi Meng, Ph.D.
Department of Computer Science
State University of New York at Binghamton

October 11th @ 3:45 p.m. 228 MSB

 

Abstract:
The Web consists of millions of databases accessible through special Web query interfaces. In recent years, there have been much efforts in developing techniques to make the data in these databases accessible in an integrated manner. In this talk, I will first compare the two leading paradigms in achieving such an integrated access, Surfacing and Metasearching. Surfacing applies deep crawling techniques to collect data from these Web databases and indexes them just like regular Web pages for centralized search. Metasearching provides a mechanism to interact with multiple Web databases and gather results from them for each query in an integrated manner on the fly. Then I will outline the main research problems under the metasearching paradigm and report some of our more recent efforts/results in tackling some of these research problems, including automatic annotation of the search results and system prototying. I will also briefly introduce some ongoing work and future directions in this topic.
