A Language for Quality of Service Requirements Specification in Web Services Orchestrations [chapter]

Fabien Baligand, Didier Le Botlan, Thomas Ledoux, Pierre Combes
2007 Lecture Notes in Computer Science  
In this context, solutions to specify service compositions (mostly BPEL language) and Quality of Service (QoS) of individual services have emerged.  ...  Our tool is responsible for the QoS constraints processing and for QoS mechanisms injection into the orchestration.  ...  Our first contribution is a language, called "QoSL4BP" (Quality of Service Language for Business Process), that allows the architect to specify QoS constraints and mechanisms in their orchestration.  ...

DRain: An Engine for Quality-of-Result Driven Process-Based Data Analytics [chapter]

Aitor Murguzur, Johannes M. Schleicher, Hong-Linh Truong, Salvador Trujillo, Schahram Dustdar
2014 Lecture Notes in Computer Science  
Although current process-based solutions rise in data awareness, there is less coverage of approaches dealing with the Quality-of-Result (QoR) to assist data analytics in distributed data-intensive environments  ...  In this paper, we present the fundamental building blocks of a framework for enabling process selection and configuration through user-defined QoR at runtime.  ...  This is required in our URBEM 1 scenario where large sets of data-aware process variants interact with data services, each with particular quality constraints.  ...

Provisioning resilient, adaptive Web services-based workflow: a semantic modeling approach

C. Patel, K. Supekar, Yugyung Lee
2004 Proceedings. IEEE International Conference on Web Services, 2004.  
In this paper, we have proposed a rule-based framework, called SemWebQ, which manages workflows composed of Semantic Web Services.  ...  Further, a framework that meets the quality of service (QoS) requirements for ad hoc Internet based services is rarely provided.  ...  Automatic management of Web Service flow requires subsequent processes of (1) discovery of Web Services considering specified constraints (2) composition of new services through automatic selection (  ...

Context-Aware Composition of E-services [chapter]

L. Baresi, D. Bianchini, V. De Antonellis, M. G. Fugini, B. Pernici, P. Plebani
2003 Lecture Notes in Computer Science  
E-Services are described in terms of functionality and quality of service. The context describes the channels that can be used to access e-Services.  ...  Composition of e-Services in a multichannel environment requires taking into account the constraints imposed by the context: user profiles, geographical locations, available channels, and usable devices  ...  In this way, we define flexible processes that are able to provide and access services which are adequate to the context available to the user.  ...

A Service Oriented Architecture for Personalized Rich Media Delivery

Sascha Tonnies, Benjamin Kohncke, Patrick Hennig, Wolf-Tilo Balke
2009 2009 IEEE International Conference on Services Computing  
For improved efficiency all adaptation should be done in a service-oriented way, because a lot of adaptation modules can be reused within different adaptation workflows.  ...  In this paper we discuss the extensions of Web service frameworks, and present a first implementation of a service-oriented framework for media streaming and digital item adaptation, concentrating on the  ...  To check the quality of our approach we constructed workflows of different length, starting with Mira's workflow.
