Ontology Driven Resource Discovery in Bluetooth Based M-Marketplace

We present a semantic-based approach to resource retrieval in an m-commerce scenario. We enhance the original Bluetooth service discovery protocol by integrating a "semantic layer" within the application level of the standard. Given a user request, this layer makes possible a matchmaking process exploiting the semantics of the resources descriptions exposed by a hotspot. It computes the match degree between the request and the goods available in the m-marketplace taking into account both their ontology-based descriptions and "classical" attributes such as price difference, availability, quantity
