A conceptual framework for development of context-aware location-based services on smart-M3 platform

Abstract

The paper presents a conceptual framework for development of context-aware location-based services. This framework provides relevant objects from the database to the user taking his/her preferences and context into account. It is based on the framework for context-aware preference queries, which provides a model of context- and preference-aware system based on the database, and the open source Smart-M3 platform, which allows to develop intelligent services using the smart space paradigm. The main components of the proposed framework include context-aware preference term generators that translate context information into context-aware preference terms, and a preference query executor that combines all preference terms and conducts their execution using PreferenceSQL JDBC driver. Evaluation of the proposed approach is made using the case study of context-aware restaurant data retrieval
