| 摘要: |
| 基于信任度评估的思想,从软件服务选取的角度对此问题进行了探讨,提出一种面向网构软件体系结构的信任驱动的服务选取机制:首先,给出一种通用的、机器可理解的应用需求及信任演化策略描述规范;其次,采用一种基于反馈的信任形成及决策机制,并给出一个信任驱动的服务选取算法;最后,给出一种面向网构软件体系结构的信任驱动的服务选取支撑框架.初步实践表明,上述机制为开发可信网构软件提供了有效支持. |

| Abstract: |
| Based on the idea of trust evaluation, this paper proposes an Internetware software architecture oriented trust-driven mechanism for selecting services to solve the problem from the aspect of service selection: Firstly, a general, machine-readable description mechanism is proposed to express user requirements and trust evolution policies; secondly, a feed-back trust formation and decision mechanism is introduced and a trust-driven algorithm for selecting services is given; finally, an Internetware software architecture oriented trust-driven service selection framework is proposed for the development of trustable Internetwares. Some development examples indicate that this mechanism can support the development of the trustable Internetwares effectively. |
