A fundamental challenge in service-oriented computing (SOC) is to select trustworthy Service. Existing approaches for service selection fail to capture the dynamic trust relationships between stranger services. Automatic trust negotiation (ATN)is a new approach to establish trust between strangers on the internet through the bilateral exchange of digital credentials. When a credential contains sensitive...
Service discovery is the premise of service composition. The existing service discovery methods only consider individual service functions and static properties, less considering the inherent dependencies between the composite services. The data dependencies between services reveal the logic correlation between the composite services, but it is of great significance for the service composition and...
Organization, flow and technology are three foundation of regulatory compliance. On the foundation there are three dimensionality of frame security for web service based on regulatory compliance: protection, monitor and audit. The blue print of security for web service based on regulatory compliance should describe the right and responsibility for every role, stabilization of basic structure, safety...
This paper tries to design structure of Web-Based Service Management of Distributed Learning (WSMDL). The structure integrating IT service and Educational Auxiliary System service flow. Help desk becomes only interface for all levels of users according to their individual demands. Though analysis of service events and userpsilas feedback in service flow, it also provides the decision-making to improve...
Thanks to standard specifications for Web services, more and more data is represented and exchanged in XML. Efficiently finding all occurrences of a twig pattern is a core operation of XML query processing. Recently, a large number of holistic twig join algorithms have been proposed, however ordered XML twig join has been ignored in most of them. In this paper we design a novel algorithm called OTJFast...
The ant colony optimization (ACO) algorithm is a metaheuristic inspired from the behavior of foraging ants. Instead of exploring its ability in finding optimal solutions, the current study investigates another unique property - self-healing mechanism for resource allocation in a service-oriented environment where unexpected resource breakdown can occur. A system architecture is first proposed to detect,...
With an increasing complexity of business processes, self-healing capability is becoming an important issue in order to support robust service flow execution. In this paper, a dynamic self-healing mechanism is proposed, which can dynamically identify suitable alternatives and replace faulty services such that a service flow can be performed successfully despite of unexpected exceptions. This mechanism...
Globalization leads to an efficient new business paradigm generally known as collaborative virtual enterprise (CVE) which demands flexible service orchestration and robust workflow execution. As two major service orchestration strategies, OWL-S and BPEL have their own strength and deficiencies. To meet the challenge in CVE, in this paper, we propose a workflow execution system (WES) that takes advantage...
Self-healing in workflow is becoming prominent because of the increasing software complexity. In order to support robust workflow execution, in this paper, we propose a self-healing mechanism to replace the faulty service dynamically. It is based on our previous research work -workflow execution system (WES). The OWLS2BPEL Mapper in WES is further enhanced to embed the self-healing mechanism into...
Collaborative virtual enterprise (CVE) is a new paradigm for industry and it imposes significant challenges on effective operation. In this paper, we formalized a top-down methodology for designing and developing service-oriented CVE with rich semantic support. This methodology facilitates automatic execution of virtual business process via service composition. The semantic notion is emphasized as...
Determining the service composition strategy suitable for service-oriented applications is an essential design issue. As a first step towards understanding service composition, in this paper, we present a comparison study with two different service composition strategies. One is driven by industrial application - BPEL, the other is inspired by the booming research development in semantic web - OWL-S...
Collaborative virtual enterprise (CVE) is a new paradigm for industry and it imposes significant challenges on effective operation. In this paper, we address the dynamic integration by leveraging the emerging Semantic Web services technologies. An integration architecture is introduced first for constructing a semantic-rich service-oriented CVE. A semantic-driven services composer based on the forward-chaining...
