Exploiting E-C-A Rules for Defining and Processing Context-Aware Push Messages

• 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.
