This paper introduces an extended service oriented architecture that provides separate tiers for composing and coordinating services and for managing services in an open marketplace by employing grid services.Abstract:
Service-oriented computing (SOC) is the computing paradigm that utilizes services as fundamental elements for developing applications/solutions. To build the service model, SOC relies on the service oriented architecture (SOA), which is a way of reorganizing software applications and infrastructure into a set of interacting services. However, the basic SOA does not address overarching concerns such as management, service orchestration, service transaction management and coordination, security, and other concerns that apply to all components in a service architecture. In this paper we introduce an extended service oriented architecture that provides separate tiers for composing and coordinating services and for managing services in an open marketplace by employing grid services.read more

Predicting Quality of Service for Selection by Neighborhood-Based Collaborative Filtering
TL;DR: A neighborhood-based collaborative filtering approach to predict such unknown values for QoS-based selection and has three new features: the adjusted-cosine-based similarity calculation to remove the impact of different QoS scale; a data smoothing process to improve prediction accuracy; and a similarity fusion approach to handle the data sparsity problem.

Business process execution language for web services
TL;DR: This book focuses on executable processes and comes back to abstract processes in Chapter 4, which can be used to replace sets of rules usually expressed in natural language, which is often ambiguous.

Grid services for distributed system integration
TL;DR: In this paper, the authors focus on the nature of the services that respond to protocol messages and propose a set of services that can be aggregated in various ways to meet the needs of virtual organizations, which themselves can be defined by the services they operate and share.
Web Services Coordination (WS- Coordination)
TL;DR: This specification describes an extensible framework for providing protocols that coordinate the actions of distributed applications, used to support a number of applications, including those that need to reach consistent agreement on the outcome of distributed transactions.
Grid Service Specification
TL;DR: Technical details are provided, providing a full specification of the behaviors and Web Service Definition Language (WSDL) interfaces that define a Grid service.
