Title: Toward Large-Scale Integration: Building a MetaQuerier for the Deep Web Speaker: Kevin Chang (UIUC) Abstract: Over the past few years, the Web has deepened dramatically. Much information is now hidden on the "deep Web," behind the query interfaces of numerous searchable databases-- Our 2004 survey estimated 450,000 online databases and 1,258,000 query interfaces. To enable effective access to the deep Web, the MetaQuerier project at UIUC aims at both finding and querying such online databases. In this talk, I will discuss a few "lessons" learned to date, focusing on issues and insights in building a large-scale integration system. In particular, I will argue that, while the deep Web challenges us for large scale integration, the challenge itself presents a unique opportunity for shallow, holistic integration approaches-- We thus propose to tackle the "deep" semantics by exploring "shallow" syntactic and statistic clues hidden across large scale of sources, holistically.
