Toward large scale integration: Building a MetaQuerier over databases on the Web
Kevin Chen Chuan Chang, Bin He, Zhen Zhang · 2005
The Web has been rapidly "deepened" by myriad searchable databases online, where data are hidden behind query interfaces. Toward large scale integration over this "deep Web," we have been building the MetaQuerier system-- for both exploring (to find) and integrating (to query) databases on the Web. As an interim report, first, this paper proposes our goal of the MetaQuerier for Web-scale integration-- With its dynamic and ad-hoc nature, such large scale integration mandates both dynamic source discovery and on-thefly query translation. Second, we present the system architecture and underlying technology of key subsystems in our ongoing implementation.
