Abstract: Service oriented computing is becoming the standard paradigm to support the creation of applications composed of eservices selected from a registry. Nowadays, we are assisting to the proliferation of standardized approaches to describe such services, but there is the general agreement of distinguishing the general characteristics of services from the characteristics linked to service invocation. In many case, the selection of services is static and based on matching techniques to retrieve the most appropriate service. The paper presents theMAIS architecture to provide highly adaptive e-services in a mobile and interactive environment. It focuses on service selection and invocation, contextaware orchestration, and mechanisms for managing user interaction in a service oriented architecture. We propose adaptivity at different levels: at the process level, but also at the level of the selection of a concrete service given an abstract description. selection is based on suitable ontologies and can consider the actual context and user characteristics to retrieve the most suitable services. The paper describes the main components of the architecture and exemplifies them on a simply process for a shipping company. Download paper
