P2P Integration of Relational Knowledge Bases

Authors:
Tadeusz Pankowski

Keywords: knowledge bases; data integration; integrity constraints; data exchange; ontology-based data management

Abstract:
We discuss some strategies of query answering in a Peer-to-Peer (P2P) knowledge integration system. In such a system, a set of autonomous services (peers) manage knowledge bases, which are connected by means of mappings between signatures of these knowledge bases. A query is issued against an arbitrarily chosen peer (a target peer) and is propagated along semantic paths determined by mappings. Next, partial answers are sent back to the target peer. We discuss a strategy of both query propagation and merging partial answers with possibility of discovering some "missing values". The proposed method guarantees improvement of quality of answers (their completeness) and controlling efficiency of merging partial answers by deciding whether it is useful to involve the whole peer's knowledge base in the process of discovering missing values. %The quality of the answer (its completeness) as well as the efficiency of processing depends on ordering of the query propagation and on the way of merging partial answers. A crucial role plays a process of discovering so-called {it missing values}. We propose a method which allows to decide when it is useful to involve the whole RKB stored on the peer in the process of discovering missing values.
