In Service-Oriented Computing (SOC) environments, service clients interact with service providers for consuming services. From the viewpoint of service clients, the trust level of a service or a service provider is a critical factor to consider in service selection, particularly when a client is looking for a service from a large set of services or service providers. However, a invoked service ...

Cloud technology connects a collection of virtualized computers that are dynamically provisioned as computing resources, based on negotiated agreements between service providers and users. It delivers information technology resources in diverse forms of service, and the explosion of Cloud services on the Internet brings new challenges in Cloud service discovery and selection. To address these c...

Context-awareness has become a key issue in Human-Computer Interaction(HCI) to provide better user experience under multi-device and multi-modal environment. With this intuition, we have proposed a web service based framework, which associates interactions with services, and provided service selection mechanism using context knowledge to achieve smart interaction migration [1]. A fundamental pr...

Consumers use service selection mechanisms to decide on a service provider to interact with. Although there are various service selection mechanisms, each mechanism has different strengths and weaknesses for different settings. In this paper, we propose a novel approach for consumers to learn how to choose the most useful service selection mechanism among different alternatives in dynamic envir...

The greater and greater availability of services over the web motivates the growing interest in techniques that facilitate their re-use. A web service specification can be quite complex, including various operations and message exchange patterns. In this work, we propose a rule-based declarative representation of services, and in particular of WSDL operations, that enables the application of te...

Service-Oriented Architecture (SOA) is a paradigm for developing next generation distributed systems. SOA introduces an opportunity to build dynamically configurable distributed systems by invoking suitable services at runtime, which makes the systems being more flexible to be integrated and easily to be reused. With fast growing numbers of offered services, automatically identifying suitable s...

In this paper, we explore the automation of services’ compositions. We focus on the service selection problem. In the formulation that we consider, the problem’s inputs are constituted by a behavioral composition whose abstract services must be bound to concrete ones. The objective is to find the binding that optimizes the utility of the composition under some services level agreements. We prop...

In service oriented computing, services are the basic constructs that aims to facilitate building of business application in a more flexible and interoperable manner for enterprise collaboration. To satisfy the needs of clients and to adapt to the changing needs, service composition is performed in order to compose the various capabilities of available services. With the proliferation of servic...

This paper presents a QoS (Quality of Service) based selection and composition model for semantic web services in which the negotiation is performed with all the discovered service providers and the negotiation results are used in the selection process. In semantic web service composition, the selection can also be performed after negotiating with all the discovered service providers and the ne...
