Exploring the Web, Beyond Document Search

Professor Yi Chen

1:00pm Friday 24 February 2012, ITE 325b, UMBC

Today we rely on Web Search Engines, like Google or Bing, to find relevant documents among trillions or quadrillions of documents on the Web. The Web also contains a vast amount of structured data in a variety of domains, such as travel, products, bibliographies, finance, and social networks. Current Web search engines and web database query interfaces are insufficient to satisfy the diverse search needs of web users. The information discovery processes are further complicated by the prevalence of uncertain data. At the same time, it is infeasible to request a web user to design clean databases and write precise SQL queries. In this talk, I will discuss the challenges, opportunities, and then some of the solutions that we have developed for empowering web users for effective information search on structured data. Furthermore, I will discuss how to enable successful social search so that complex computation tasks can be accomplished by leveraging social computing.
