Abstract

In this paper we present an approach to support multi-target search over a set of web nodes. Multi-target search allows users to specify multiple interdependent search objectives. Such objectives are then fulfilled by transparently contacting multiple information sources. We present a runtime platform and a language supporting extraction and assembly of information according to users' needs. The language is based on a XML query language and adapts it to the case where information is obtained by aggregating parts distributed over multiple sites. The platform is based on mobile agents and acts as an intermediary between users and information providers.
