| 摘 要： | 基于Web服务的可信应用程序构造的一个关键问题是如何度量Web服务的可信性.在遵循Web服务特点的基础上，提出一个综合的Web服务可信性度量模型TMM4WS，从Web服务的内部实现和外部使用两方面对Web服务的可信性进行度量，开发了相应的度量支持工具TMT4WS.采用Web服务实例对提出的度量模型与工具进行了验证.实验结果表明，度量模型TMM4WS及其支持工具TMT4WS具有较好的可操作性，能够定量地度量Web服务的可信性.

| Abstract: | One crucial issue of service-based trustworthy application development is how to measure the trustworthiness of Web services. A comprehensive trustworthiness measurement model for Web services, TMM4WS, was proposed based on the unique features of Web services. The model measures the trustworthiness of a Web service in terms of both its source code and external usage. A tool called TMT4WS was developed to support the model. An empirical study was conducted on tens of Web services to validate the effectiveness of the model and its supporting tool. Experimental results show that the model and its supporting tool can be employed to provide a quantitative trustworthiness measurement of Web services. |
