A formal modeling platform for composing web servicesBuilding a robust service composition is increasingly problematic as large scales of Web service operations can now be possibly achieved through the Internet. This article proposes an effective composing platform based on a formal modeling language. In particular, Petri Nets patterns are developed for enhancing service composition modeling, workflow quality measurement and scripting productivity. By providing a visual editing module, this platform allows business application developers to exploit its composing capabilities without much requiring design time or skills.ppXML: A generic and extensible language for lifecycle modelling of platform productsThis paper presents a new language, ppXML (platform product eXtensible Markup Language), for the lifecycle modelling of platform products in agile product development for mass customization (MC). ppXML has multi-folded meanings. Firstly, ppXML provides a set of constructs that are consistent with concepts and methods widely used in platform product development (PPD) for MC. Secondly, derived from XML as a sublanguage, ppXML is a standard and yet extensible modelling language dedicated to the modelling of product variants and platforms reflecting commonality, modularity, scalability and other strategies. Thirdly, ppXML can also be extended for defining web services deployed in the computation grid of web-based decision support systems (DSS) for platform product development and mass customization. Finally, ppXML serves as a standard interface with the product platform repository and a PPD web service registry, together with a set of online facilities for data representation and transformation between different components and parties involved in the web services. ppXML complements the efforts in product lifecycle data modelling by emphasizing the strategic level of product planning using a platform approach. Development of Web-Telecom based hybrid services orchestration and execution middleware over convergence networksInfluenced by the success of Web service technologies for development and deployment of IT services, Telecom R&D community starts to adapt andbuild similar service delivery platforms, trying to manage the hard constraints in Telecom domains, such as existence of heterogeneous protocols, extensive use of asynchronous communications and real-time delivery requirements, which will open a new paradigm for Web service based voice over IP communication and also can be easily integrated in end-to-end SOA solutions. In this paper, we study both the Web-Telecom based hybrid services orchestration and execution middleware for coordinating existing Telecom services and IT services. In particular, we focus on the design and implementation Web-Telecom based hybrid service bus (WTSB), event-driven Telecom service engine (EDLE) and also the integration layer for the messages dispatching and transformation between WTSB and EDLE, which can make the EDLE service engine seamlessly integrated into WTSB. More specifically, with multimedia conferencing scenarios, we demonstrate how our hybrid services orchestration and execution middleware orchestrate multimedia conferencing communication services together, and also make performance measurement and analysis. Finally, we give the conclusions and future work.Context-aware personalization services for a residential gateway based on the OSGi platform Ideally, smart homes should make its inhabitants’ lives more comfortable by anticipating their needs and satisfying their preferences. With this aim, we introduce an approach for context-aware personalized smart homes based on two main pillars: the Open Service Gateway Initiative (OSGi) platform and the Semantic Web philosophy. By combining both fields, we enrich the OSGi service-oriented architecture by providing a semantical conceptualization of (i) services at home, (ii) contextual information and (iii) inhabitants’ preferences. This ontological structure supports reasoning about the captured behavior and inferring new knowledge.A JESS-enabled context elicitation system for providing context-aware Web servicesProviding context-aware Web services is an adaptive process of delivering contextually matched Web services to meet service requesters’ needs. We define the term “context” from two perspectives: one from service requesters; and the other from Web services. From the former perspective, context isdefined as the surrounding environment affecting requesters’ services discovery and access, such as requesters’ preferences, locations, activities, and accessible network and devices. From the latter perspective, context is defined as the surrounding environment affecting Web services delivery and execution, such as networks and protocols for service binding, devices and platforms for service execution, and so on. This paper presents a Java Expert System Shell (JESS)-enabled context elicitation system featuring an ontology-based context model that formally describes and acquires contextual information pertaining to service requesters and Web services. Based on the context elicitation system, we present a context-aware services-oriented architecture for providing context-aware Web service request, publication, and discovery. Implementation details of the context elicitation system and the evaluation results of context-aware service provision are also reported.基于JESS技术的可进行内容感知的客户个性化网络服务Business processes oriented heterogeneous systems integration platform for networked enterprises基于商业运作过程的网络化企业集成平台网络构造Supply chains, dynamic alliances, e-business, extended enterprises, and virtual organizations are typical networked enterprises which are formed based on partner companies’ core competencies. Different partners have different infrastructures; the interoperability among heterogeneous systems is the solid foundation for the networked enterprise to work seamlessly and effectively. Due to the distributed and heterogeneous characteristics of different partner companies, it is a big challenge to implement a satisfying and cost effective solution in the networked enterprise.Aiming at the problems of system integration and cross-system interoperability, Service-Oriented Architecture (SOA) provides a new integration pattern and relative system infrastructure. The key for the development and implementation of SOA is services encapsulation and orchestration of applications through certain mechanism to operate a complex business. However, cross infrastructures services access protection and relative services orchestration are still the bottleneck for the SOAimplementation.This paper develops a business processes oriented heterogeneous systems integration platform with relative methodology for networked enterprises integration. The platform is a space distributed and management centralized platform for networked enterprises. The service access agent (SAA) mechanism is developed to realize cross-domains identity authentication, service authorization, and information transmission security. Every Web service or SAA in the platform has a unique ID. The interoperating process only relies on IDs, which endows the platform with a loose coupling feature. Aiming at service orchestration, a graphic service process modelling method is developed, with which the developed process model can link atom Web services and form a complex service. The Java based service orchestration tool provides an ESB (Enterprise Service Bus) independent service orchestration and deployment. Those services that are results of orchestration can be orchestrated as an atom service in another orchestrating process. Thus, the platform can support orchestration decomposition. The structure approach of the business process modelling based platform implementation is developed, which provides a guideline for platform installation, services modelling, service encapsulation, service orchestration, and service deployment. Two cases are provided to illustrate the usage of the platform in industries. The development of this platform is an open source project.A platform for transcoding heterogeneous markup documents using ontology-based metadataAs new standards, markup languages, protocols, and client devices continue to emerge, the main problem of existing transcoding systems is the lack of intelligence to cope with the heterogeneous effects, including various transcoding policies, markup documents, device constraints, and server platforms. This study proposes a new approach, called hybrid transcoding, to combine the traditional transcoding technologies based on ontology-based metadata to improve these heterogeneous problems. Additionally, the heterogeneous markup document transcoding (HMDT) platform, based on the proposed hybrid transcoding and web services technologies, is also presented to serve as a transcoding service broker to facilitate interoperabilitybetween distributed heterogeneous transcoders. To demonstrate the feasibility of HMDT platform, an application scenario of hybrid transcoding is implemented to convert HTML forms into various client devices. Knowledge-based platform for eGovernment agents: A Web-based solution using semantic technologiesCurrently eGovernment is clearly gaining momentum in our society. Many solutions and projects are being developed and, among the large amount of used tools, semantics is called to play a paramount role. In order to overcome issues related to cooperation, interoperability and accessibility of services in the domain, semantics can be used to improve in-use solutions and to develop new mechanisms able to support the development of expert and intelligent systems in eGovernment. This paper addresses a semantic based philosophy to tackle a holistic platform for the domain taking into account the knowledge of the administrations. By means of intelligent documents and Life Events, as they are presented in the paper, it is possible to build up a intelligent platform to host eGovernment services, as proved by the successful study case Tecut portal.An integrated information system for real estate agency-based on service-oriented architectureTo enhance the efficiency of surfing the Internet, an integrated platform for real estate agency-based on service-oriented architecture (SOA) is established. It employs the concept of search engine and loads the information provided previously by each real estate agency to this platform. Due to the different types of data structure from each real estate agency website, the standard format must be defined for integrating the information. In this paper, the standard is defined by XML and is used to integrate heterogeneous database. This standard format includes the data fields that are required by the agency websites. It is processed in the platform which is expandable by receiving information from other sources in the future. In consideration of the copyright regulation, the agents are allowed to login and to share specific information on this platform in order to increase thetransaction rate. The system also includes a Google Map engine for GIS service that marks the spatial location as the users send the requests. It helps the users to find the demanded housing information and to retrieve the nearby geographic location in a very short time.A Web services and process-view combined approach for process management of collaborative product developmentCollaborative Product Development (CPD) across enterprises has been recognized as an effective strategy to connect multi-enterprise wide project teams to develop more competitive products. Process management is vital to the successful implementation of CPD in a multi-enterprise environment. In this paper, a novel Web Services (WSs) and process-view combined approach has been developed to manage the dynamic and distributed process of CPD to enhance the workflow interoperability among heterogeneous Workflow Management Systems (WMSs) of enterprises. Meanwhile, a hybrid P2P based WMSs framework has been built to provide an open and scalable architecture to deploy inter-enterprises collaboration. A software prototype system has been implemented using the open JXTA platform, and the collaborative development of a motorcycle has been used as a test case to validate the proposed approach and the prototype system.协同化产品开发过程管理软件/网站中，将网络服务与业务过程层捆绑的方法Automating the manufacturing process under a web based framework基于网络的自动化生产过程框架The rapid evolution of the web has affected the way under which the manufacturing process is practised. In this paper, a web based framework –independent from any specific CAD/CAM software – is proposed, for employing electronic interaction between designers and manufacturers. In this context, designers and manufacturers communicate for the manufacturing of a workpiece, under a platform-independent, easier, faster and moreeconomical way. The proposed framework is implemented as a web service, where the Simple Object Access Protocol (SOAP) is used for the exchange of the necessary machined parts data and the methodologies of UDDI (Universal Description Discovery and Integration) and WSDL (Web Services Description Language) are introduced for providing directories and descriptions information.。
