Intelligent Query Management in a Mediator Architecture

This paper presents a new technology aimed at supporting the user in the process of building a query to a catalogue of products. It is shown how a mediator architecture can be extended to support the relaxation or tightening of query constraints when no or too many results are retrieved from the catalogue. This paper presents the architecture and the basic algorithms of this Intelligent Mediator. An application of this technology to a recommendation system for travel products selection is also illustrated
