A Top-Down Methodology for Building Semantic-Rich Service-Oriented Collaborative Virtual Enterprise (CVE)

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 algorithm is then presented and implemented to realize dynamic integration. Its successful application in a prototyped enterprise manufacturing system further exemplifies the practicality of semantic web service technologies in supporting collaborative virtual enterprises.

Several e-business frameworks are developed to define standards for information sharing within and between companies. These frameworks only standardize structure of messages and aren't able to define semantics. It leads to slow and costly dynamic Business-to-Business (B2B) integration. The use of Semantic Web Service (SWS) technologies has been suggested to enable more dynamic B2B integration of heterogeneous systems and partners. We present a semantic B2B mediator based on the WSMX-a SWS execution environment, to tackle heterogeneities in B2B services. We particularly show how WSMX can be made to support the RosettaNet e-business framework and how it can add dynamics to B2B interactions by automating mediation of heterogeneous messages. We used a reasoner in interaction with WSMX for automatic consistency checking of instances in runtime. The benefits of applying SWS technologies include more flexibility in accepting heterogeneity in B2B integrations and easing back-end integrations. This allows introducing more competition into the purchasing process within e-business frameworks.

A semantic web service environment for B2B and B2C auction applications within extended and virtual enterprises

Firstly, this paper expounded that the traditional searching based on keywords has a severe deficiency on Recall and Precision because the computer can't understand what information mean efficiently. In Succession, through extending from ordinary information to Geo-spatial information, on the support of geo-ontology theory and semantic web services technology, this paper discussed the principle, methods and application of ontology-driven geo-spatial information retrieving mechanism in semantic web. In other word, How to structure the framework for running this mechanism, how to build the ontology information models and how to establish the ontology-driven services models are discussed in detail in context. A design of systems for implementing the mechanism and experiment are given at the end of the text.

In mass services environment, how to schedule resources efficiently and reliably in the Fourth Party Logistics is a hot topic recently. Semantic web and web service technology are introduced into our project on the background of 4PL. The starting point of our work is to define service conceptions, semantic matching and reasoning in logistic. Then, two-stage solution algorithm (TSSA) is proposed which always can figure out solutions with low time-consuming and makes the platform more interactive. In the 1 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">st</sup> stage, a semantic-driven dynamic logistic services composition algorithm is offered in the project, which is the improvement of classical Ant Colony algorithm. It can figure out a couple of logistic service paths at one time and the paths are the input of the 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">nd</sup> stage. TSSA optimize the results based on Q OS and complexity of TSSA is polynomial-time which is much better than that of classical Ant Colony algorithm‥ In order to improve calculation for QoS, a trust and reputation enhanced QoS calculation method is presented on the light of Bayes learning theory. At last, with implementing TSSA in different logistic environments and compared its results with that of classical Ant Colony algorithm, the results show that TSSA can quickly and effectively get solutions meeting customers' requirements well.

The use of Semantic Web Service (SWS) technologies have been suggested to enable more dynamic B2B integration of heterogeneous systems and partners. We present how we add semantics to RosettaNet specifications to enable the WSMX SWS environment to automate mediation of messages. The benefits of applying SWS technologies include flexibility in accepting heterogeneity in B2B integrations.

Web services technologies are emerging as a new approach for supporting e-science and e-engineering by providing access to heterogeneous computation resources and integration of distributed scientific applications. In this paper, we propose a Web portal architecture that enables end users to access the distributed application through the Web interface and to compose new tasks by integrating a set of high level Web services provided by portal developers. The portal design demonstrates that flexibility, reusability and interoperability can be provided for both end users and portal developers by using semantic Web services technologies.

Interoperability between management systems is significantly altered by an overload of data, along with syntactic and semantic dissonance of management information. New service-oriented architectures have been proposed to facilitate the decentralization of the control and to add more flexibility in the management process. However, a little was done towards the reuse of legacy information in nowadays modeling framework. In this paper, we demonstrate how existing information definition can be reused and integrated using semantic Web technologies. Our objective is to enhance SNMP and WBEM solutions with semantic Web services technologies, thus, allowing interoperability between heterogeneous systems and truly facilitating the design, the deployment and the maintenance of network management systems.

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 BPEL workflow by exploiting Semantic Web service technology. In order to realize service substitution, business rules is utilized to model the essential business logic behind the service interface (local business rules) and the service selection policy of a composite service (global business rules) in a domain-dependent and semantic-rich manner. A concrete scenario in PC manufacturing collaborative virtual enterprise is presented to test our self-healing capable workflow execution system.

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. We compare the two major strategies with each other through the collaborative virtual enterprise (CVE) scenario. Five key dimensions for service composition requirement have been identified These dimensions belong to two types. One type of dimensions is essential requirement including component model, orchestration model and data flow model. The other type is desirable requirement including error handler and transaction, and quality of service. We provide the comparison between BPEL and OWL-S against the five dimensions. Our comparison shows that OWL-S is more suitable for dynamic environments and BPEL is an ideal choice for controlled workflow.

Semantics is applied into Business Process Management (BPM) to bridge the gap between the business world and information systems, especially in the context of B2B integration. Current standards such as BPMN, XPDL, BPEL and their combination have not fulfilled the expectation of two communities. The gap is still there: how enterprises can make the cross collaboration each other without ‘knowing’ their partners; and how a process based on the graphical notation can be fully mapped into the executable process without its semantics. In this paper, we propose a new approach, namely BizKB framework, for the cross-enterprise integration using ontologies and Semantic Web Services technologies in order to realizing business concepts into the executable level using web services.KeywordsBusiness ProcessBusiness Process ManagementBusiness Process Modeling NotationInterchange StandardSemantic BusinessThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Traditional EA concepts in the Enterprise Application Integration (EAI) domain focus on ex-post integration of application interfaces by pipelining different middleware technologies like message queuing or remote method invocations [1, 2]. Web Service enabled Service-Oriented Architectures (SOAs) used in the EAI context were a step towards providing an abstraction layer for the involved interfaces by using the Web Service Description Language (WSDL). The idea of SOA enlarges by applying Semantic Web Services (SWS) technology to it. OWL-S and WSMO are two examples for concrete implementation approaches in this area [3, 4], and we will demonstrate semantic WSMO framework, and how it can solve the problems of traditional SOA.

Web is a place for information sharing as well as service providing. With the addition of Service Oriented Architecture ensures better reusability, maintainability and flexibility among the heterogeneous data sources. Possibility of a better interoperability within such a heterogeneous data sources is less without further assistance. For better service discovery, these issues must be cleared first. Besides this, security measures also play a key role. By developing a Multiagent based middleware system can resolve all these issues. Further it will add up better communication among the different modules of the system as well as the self learning capability. This paper’s approach is aimed to the development of Multiagent system based middleware architecture for better service discovery, selection and invocation through a secure way without replacing the existing services based on Web Service and Semantic Web Service technologies. The architecture will use ontologies heavily to introduce the rich semantics to the services to provide better meaning understandable by machines.

The Web Services technology failed to meet its promises of fully automating the communication between applications. It necessitated human intervention in the selection and invocation of the most appropriate web service. The Web Service Modeling Ontology (WSMO) and the Web Service Modeling eXecution environment (WSMX) are two initiatives claiming to be supporting the Semantic Web Services technology, which promises the automation of the whole communication process including these two steps. The paper tested validity of the initiatives' claim by using them to develop a Semantic Web Service (SWS) for accessing the publications of the German University in Cairo (GUC). The results showed that the initiatives were able to meet the Semantic Web Services' promises and automate the selection and the invocation of the most matching Web Service.
