document: An active functionality service for e-business applications Service based architectures are a powerful approach to meet the fast evolution of business rules and the corresponding software . An active functionality service that detects events and involves the appropriate business rules is a critical component of such a service-based middleware architecture . In this paper we present an active functionality service that is capable of detecting events in heterogeneous environments , it uses an integral ontology-based approach for the semantic interpretation of heterogeneous events and data , and provides notifications through a publish/subscribe notification mechanism . The power of this approach is illustrated with the help of an auction application and through the personalization of car and driver portals in Internet-enabled vehicles
