The aim of this paper is proposing a configurable architecture for implementing e-learning service management, taking into account several diverse aspects concerning not only the educational process, but also network infrastructure, the QoS requirements, the types of educational content, etc. We present a flexible, parametrical and component-oriented management scheme, which dynamically creates...

Electronic commerce (e-commerce) is getting more and more important in people’s every day shopping routines. Vendors who want to establish an online channel besides their traditional retail practice have to integrate the two supply chains. The underlying information technology systems should be able to support the integration of the new and old processes. While reference models are a popular me...

The purpose of this study is to define generic service processes, their system, and a scope of service science developed originally by the author. In the presented approach, the main criterion is the class of serviced users, since this leads to the six kinds of process recognition and eventually helps in planning e-service systems’ architecture. E-service system (e-SS) is defined as a mission-g...

Message-based Web Service architecture provides a unified approach to applications and Web Services that incorporates the flexibility of messaging and distributed components. We propose SMMV and MMMV collaboration as the general architecture of collaboration based on a Web service model, which accommodates both instructor-led learning and participatory learning. This approach derives from our m...

Electronic contracts describe inter-organizational business processes in terms of supply and consumption of electronic services (commonly Web services). In a given contract domain, it is usually possible to identify a set of welldefined common and variation points. Feature modeling is an ontology-like technique that has been widely used for capturing and managing commonalities and variabilities...

Current developments show that tomorrow’s information systems and applications will no longer be based on monolithic architectures that encompass all the functionality. Rather, the emerging need for distribution and quick adaptation to new requirements stemming from, e.g., virtual enterprises, demands distributed systems that can be extended dynamically to compose new services from existing sof...

E-mail brings us lots of conveniences. Especially with help of PGP and S/MIME, it gives both confidentiality and message/origin authentication. However, in some cases for strong privacy, a message sender will not want to let others know even the fact that he sent a message to a recipient. Very recently, Harn and Ren proposed a fully deniable authentication scheme for E-mail where a sender can r...

Nowadays Service activities are social and involve different types of individuals that should be considered. Thus, group profiling can be used to connect similar customers together and recommend providers based on group evaluation. Accordingly, this paper proposes a new approach that recommends providers, based on group profiling and ranking, to be used in e-service portals. This approach focus...
