Dewex: An Exploration Facility for Enabling the Deep Web Integration

In this demo, we present Dewex, an exploration facility for answering questions like T1-TA, running on repository of over 30,000 real sources. The main technical contributions of this demo are: as our system, we present a novel facility for exploring the deep Web; as our solution, we propose a schematic metadata based source modeling, and a generalized search mechanism to compute associativity in metadata graph; and in our realization, to enable online exploration, we propose to speed up computation using matrix optimization.
