A Peer-to-Peer Based Semantic Agreement Approach for Information Systems Interoperability

This paper focuses on P2P based data management and semantic mediation. We propose an approach based on a P2P for semantic interoperability of information sources that aims to combine the advantages of semantic mediation and peer-to-peer systems. It is based on a pure P2P with super peer architecture consisting of two types of peers. The super peer contains a reference ontology, which provides a common ontology (CO) of the domain. The peer contains export schema (ES), which represent local data. The approach based on semantic agreement between CO and ES, which called half agreement (HA). The halfagreements utilize for discovery sources and exchange information among peers.
