Title: Meta Web Search with KOMET

Authors: Jacques Calmet, Peter Kullmann.

Abstract KOMET is a logic-based mediator system that was designed for the knowledge-based integration of heterogeneous information sources \cite{komet}. One of the main challenges in using the numerous information sources in the World Wide Web is to cope with their heterogeneity. In this work we demonstrate how popular web search services like Yahoo and AltaVista can be combined in the framework of KOMET to obtain more useful search results. By gradually increasing the complexity of the meta search application, we demonstrate different features of the KOMET system. Finally, we discuss future developments in KOMET in the light of this example application.
