In this paper we present the architecture of a system for searching and querying information sources available on the web which was developed as part of a project called WISDOM. key feature of our proposal is a distributed architecture based on (i) the peer-to-peer paradigm and (ii) the adoption of domainontologies. at the lower level, we support a strong, ontology-based integration of the information content of a bunch of source peers, which form a so-called semantic peer. at the upper level, we provide a loose, mapping-based integrationof a set of semantic peers. we then show how queries can be efficiently managed and distributed in such a two-layer scenario.

Abstract
In this paper we present the architecture of a system for searching and querying information sources available on the web which was developed as part of a project called WISDOM. key feature of our proposal is a distributed architecture based on (i) the peer-to-peer paradigm and (ii) the adoption of domainontologies. at the lower level, we support a strong, ontology-based integration of the information content of a bunch of source peers, which form a so-called semantic peer. at the upper level, we provide a loose, mapping-based integrationof a set of semantic peers. we then show how queries can be efficiently managed and distributed in such a two-layer scenario.
