The social network of the Internet is interpreted as the consequences of invisible connection between humans. In the graph based studies the nodes are human beings and the edges represent various social relationships. SLN is a loosely coupled, self-organized semantic data model that link resources semantically. The interactions among users can be interpreted via SLN formation and evolution The interactive...
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...
