CASCOM: Intelligent Service
Coordination
in the
Semantic
Web
Michael Schumacher,
Heikki Helin and
Heiko Schuldt, Editors
A general architecture for service delivery and coordination in intelligent agent-based
peer-to-peer (IP2P) environments, that has been developed within the CASCOM research
project, is presented in this book. The CASCOM architecture provides support for business
services for mobile workers and users across mobile and fixed networks.To its users,
the CASCOM architecture makes easy and seamless access available to Semantic
Web Services anytime, anywhere, and using any device. The system has successfully
been validated in trials in healthcare applications, in particular in emergency medical
assistance. The CASCOM architecture addresses the problem of seamlessly combining
various novel technologies that establish the basis for self-adaptable and self-healing
systems including semantic service discovery, matchmaking, composition planning and
semantic service composition, reliable execution of composite services, and semantic
failure handling. The book provides an in-depth introduction into these areas, presents
how they have been extended in order to best support the needs for agent-based service
coordination in IP2P environment, and finally shows how the different agents can be
seamlessly combined.

CASCOM: Intelligent Service
Coordination
in the
Semantic
Web
Michael Schumacher,
Heikki Helin and
Heiko Schuldt, Editors
A general architecture for service delivery and coordination in intelligent agent-based
peer-to-peer (IP2P) environments, that has been developed within the CASCOM research
project, is presented in this book. The CASCOM architecture provides support for business
services for mobile workers and users across mobile and fixed networks.To its users,
the CASCOM architecture makes easy and seamless access available to Semantic
Web Services anytime, anywhere, and using any device. The system has successfully
been validated in trials in healthcare applications, in particular in emergency medical
assistance. The CASCOM architecture addresses the problem of seamlessly combining
various novel technologies that establish the basis for self-adaptable and self-healing
systems including semantic service discovery, matchmaking, composition planning and
semantic service composition, reliable execution of composite services, and semantic
failure handling. The book provides an in-depth introduction into these areas, presents
how they have been extended in order to best support the needs for agent-based service
coordination in IP2P environment, and finally shows how the different agents can be
seamlessly combined. |
