The infonnation' heterogeneity that arises from the autonomy of peers is a major problem for sharing infonnation in peer-to-peer (P2P) systems. This problem is hugely complicated by the dynamic and scalable natures of these systems. Many approaches have been proposed for infonnation sharing in P2P systems with heterogeneous p~ers. I have been particularly interested in dynamic ontology matching and integration in addressing this issue. However most ontology matching and integration approaches are either semi automatic, requiring final user judgement or not accurate enough to be used without human intervention. I am confident that in this research I have successfully addressed these issues.I have developed an integration model with layered structure for schema, ontologies and mal?pings/or Data. and Knowledge Sharing Peer to Peer (DAKSIP2P) systems. A representation scheme for ontologies has been presented with a set of rules to avoid conflicts that cannot be handled without human input. Within this representation scheme, a dynamic ontology matching and integration algorithm has been produced to match and integrate peer and coalition ontologies.
