Ontology-based data source localization in a structured peer-to-peer environment

Published: 10 September 2008 Publication History

Abstract

In Peer-to-Peer environments, the absence of a global schema makes locating data sources a real problem. Semantic and structural heterogeneity of local schemas prevent the localization phase to find relevant data sources for a given SQL query. Useless information obtained during this phase could not only lead to incorrect answers but also it is expensive in terms of resource consumption. In this paper, we propose a method integrating domain ontology into Chord protocol. This integration provides comprehensive data exchange while carrying out efficient data source localization. Before the localization phase, the terms of the given SQL query must be written according to the domain ontology which forms the only interface to interact between peers. Chord protocol is extended by Structure Indexes that describe the relation structures. The proposed method allows extended Chord protocol to select relevant data sources and to avoid useless information. We present simulation results showing the feasibility of our method and its benefits.
