中文摘要： 信息服务选择是实现服务共享、复用的重要前提，服务选择的结果直接影响服务请求者是否能成功获取网络中的服务资源。随着网络服务场景的变化，移动互联网、电子商务、远程医疗等新兴服务运行环境的出现，服务选择的可信需求日益增强，现有的服务选择方法面临挑战。本项目致力于解决可信驱动场景下的服务选择问题，通过对可信驱动的服务选择需求的深入分析，利用协同过滤技术、信任机制相关理论与成果研究服务可信联盟机制的实现；提出支持语义关联的可信服务选择方法，提高组合服务的正确性与高效性；研究服务的可靠性，利用软件容错理论实现可信驱动的冗余服务选择机制，提高服务选择结果的可靠性与有效性；在理论研究基础上开发可信驱动的服务选择原型系统，并建立一个远程医疗服务场景下的可信在线诊断应用示范。项目的研究工作对促进信息服务新兴应用的推广具有十分重要的理论意义和参考价值。

英文摘要： Information services selection is one of the crucial premises to the realization of service sharing and reuse. The results of service selection will directly affect whether or not a service requester can successfully obtain the desired service. However, with the change of network environment as well as the spread of mobile internet, e-commerce and remote medical treatment, current service selection solutions cannot meet the requirements of trustworthiness on service selection. This project seeks to address the problem of trustworthiness-driven service selection. Firstly, with profound analysis of trustworthy requirements for service selection and employment of collaborative filtering technique combined with a theory founded in trust, trustworthy community mechanism for service selection will be established. Secondly, in order to improve the correctness and effectiveness of service selection, a semantic correlation-aware trustworthy service selection approach will be proposed. Thirdly, service reliability will be taken into account to setup a trustworthiness-driven redundant service selection mechanism. Finally, based on research results, a service selection prototype will be designed, followed with an online diagnosis application demonstration in remote medical treatment service. It is concluded that research wo
