Determining the behavior of mobile location-aware services based on user action history

Context awareness offers a powerful vision that aims to build novel services that adapt to the situation of the user. Context-aware frameworks provide functionalities for gathering data from sensors and for processing this data to interpret the user’s context. This context information is further used to adapt the behavior of services. Adaptation is often performed by applying predefined rules that associate the user’s context with some actions performed by the service. This still limits the use of context-aware services. Services can be adapted only in contexts that have been foreseen by the service designer or the user and for which rules are expressed. When the action of the service is not specified in a user’s context, the system can no longer perform adaptation. In this paper we present our approach for determining the service behavior expected by the user when no action is specified. We discuss the various steps that address this issue considering the particular case of location-aware systems, i.e. system that adapt their behavior to changes in a user’s location.
