This paper presents NGS, a framework providing fully automated support for cross-domain queries. In particular, NGS (a) integrates different kinds of services (search engines, web services, and wrapped web pages) into a global ontology, i.e., a unified view of the concepts supported by the available services, (b) covers query formulation aspects over the global ontology, and query rewriting in terms of the actual services, and (c) offers several optimization opportunities leveraging the characteristics of the different services at hand, based on several different cost metrics.
