- A context-aware information push service provides the user with tailored information regarding her/his actual situation (the actual situation is also referred as context). This paper motivates and discusses the development of a context-aware information push service. A survey is presented motivating the implementation of such a system. Further, key requirements are identified leading to a description of the system architecture, thereby giving insight into how the requirements are tackled. Finally, the rule language which is used to formally declare push processes and the inference engine translating such rules into concrete push messages is explained in detail. The push service presented in this paper is part of the overall etPlanner system, a framework for mobile tourist guides

Konferensbidrag (refereegranskat)abstract
- The focus of this paper is to show that the E-C-A paradigm offers an excellent approach for specifying the behavior of context-aware information push services. Such a service enables its operator to provide the users with tailored messages related to their current situation (context). The paper introduces CAIPS, an implementation of such a service for the tourism domain. The underlying E-C-A rules are presented and the design of the associated rule-engine is described. The engine’s rule-interpreter is based on event-notification services and the object-oriented query-language HQL. The paper further presents a graphical high-level editor which supports business-experts in “writing” the CAIPS E-C-A rules. The presented approach enables the rapid development of new tailored messages (related to the user’s context) without the need to modify the underlying application, i.e. without the trouble of writing new code for new message types.
