中文摘要: 随着面向服务计算的应用越来越广泛,高效的语义Web服务选择已成为Web服务领域迫切需要解决的问题。在Web2.0环境下,用户对Web服务的反馈可被用来评价Web服务的非功能属性和分析用户的个性化偏好,因此,研究基于用户反馈的非功能属性评价与用户偏好分析的语义Web服务选择方法,对于提高Web服务选择效果具有重要意义。本项目将首先从Web2.0环境下用户反馈对Web服务非功能属性评价的影响出发,研究整合用户反馈的语义Web服务非功能属性描述本体的设计与构建方法;然后结合信息抽取的最新进展,研究从用户反馈信息中抽取语义Web服务非功能属性实例的方法,并结合用户的信誉度分析不同用户对语义Web服务非功能属型评价的可信程度;进一步研究用户的个性化偏好建模与分析技术及用户兴趣网络的构建方法,在此基础上研究基于用户兴趣网络的语义Web服务协同选择方法;最终建立基于用户反馈的语义Web服务协同选择工具。

英文摘要: As Service-Oriented Computing is wildly used, effective Semantic Web service selection has become an urgent task in the domain of Web service. Under Web 2.0, the users' feedback can be used to evaluate the non-functional properties of Web service and analyze the users' preference, therefore, the research of Semantic Web service selection based on the evaluation of non-functional properties and analysis of users' preference is significant in improving the effectiveness of Web service selection. This project will first analyze the influence of users' feedback on the evaluation of Semantic Web service non-functional properties under Web 2.0, then investigate the design and construction methods for non-functional properties ontology. Based on this, we will investigate the method of instance extraction for non-functional properties from users' feedback, and then analyze the trustworthiness of evaluation for non-functional properties according to users' reputation. After that, we will investigate the modeling and analyzing techniques of users' preference and the method of construting users' interest network. Further, we will investigate the collaborative Semantic Web service selection method based on users' interest network. Finally, we will build and implement the prototype of collaborative Semantic Web service selec
