Adaptive query processing for semantic interoperable information systems

Abstract

We present an adaptive query processing approach for semantic interoperable information systems. The algorithm is self-adapted to the changes of the environment, offers a wide aptitude and solves the various data conflicts in a dynamic way, it reformulates the query using the schema mediation method for the discovered systems and the context mediation for the other systems. Another advantage of our approach consists in the exploitation of intelligent agents for query reformulation and the use of a new technology for the semantic representation. © 2011 Springer-Verlag.
