Towards the use of mediated knowledge-based and user-defined views in super-peer P2P systems

Abstract

In recent years, peer-to-peer data integration systems have attracted significant attention for their ability to communicate, collaborate and share information in a networked environment. One of the main problems that arises in such systems is how to exploit their mappings in order to answer queries posed to one peer. Our proposed framework can be used to exploit the existing mapped data together with its data location information for defining a peer's data view. This data view is expected to produce query results based on peer preferences rather than using standard query processing at the super-peer level, as practiced in current super-peer P2P systems. Our framework consists of two major components: a mediated knowledge-base at the super-peer and user-defined data views at the peer. © 2007 Springer.
