Web服务技术正在改变组织和机构部署应用的方式,现在已得到了广泛关注。Web服务最吸引人的地方在于已有服务的组合能够创建新的增值服务。为了使Web服务能够有效地组合,组合进程需要保证参与某一特定组合服务的组件服务比其他提供相同功能的服务更可信。本文分析讨论了Web服务可信的不确定性,提出Web服务可信评价方法研究路线图,倡导基于不确定性理论和方法对Web服务可信进行建模,并在其中融入系统论和社会网络的理论和方法,将基于可信的服务选择和服务组合有机地结合起来,将服务消费者的可信、服务提供者的可信与Web服务的可信有机地结合起来,解决服务消费者的个性化选择、新服务参与竞争、由组件服务可信导出组合服务可信等问题。这种新的Web服务可信评价方法应该保持普遍性和一致性,将上述几个问题的求解纳入到同一个可信评价模型。本文提出的Web服务可信研究路线图试图为Web服务可信研究提供启迪和指导。
Web services technologies are changing the way organizations and organizations deploy applications and are now receiving widespread attention. The most attractive part about Web services is that the combination of existing services creates new value-added services. In order for web services to be effectively combined, the composition process needs to ensure that component services participating in a particular composite service are more trustworthy than other services that provide the same functionality. This article analyzes and discusses the uncertainty of Web services trustworthiness, puts forward the research roadmap of Web services trustworthiness evaluation method, advocates the modeling of Web services trustworthiness based on the theory and method of uncertainty, and integrates into system theory and social network Theory and method, based on the credible combination of service choices and service combinations organically combine the credibility of service consumers, the trustworthiness of service providers and the credibility of Web services organically to solve the problem of service consumers Personalized choice, new services to participate in the competition, trusted by the component services derived credible combination of services and other issues. This new method of trusted evaluation of Web services should maintain universality and consistency, and bring the solution of the above problems into the same trusted evaluation model. The paper proposes a road map for the research of trusted Web services to provide enlightenment and guidance for the trusted research of Web services.
