【摘要】：Web服務(wù)作為網(wǎng)絡(luò)化的主要形式,其可信性問題已成為Web服務(wù)獲得進一步發(fā)展的主要障礙。但是,現(xiàn)有的Web服務(wù)技術(shù)尚沒有完整、有效的可信性描述語言,使得Web服務(wù)提供者和請求者之間難以表達自己的可信性訴求。此外,現(xiàn)有的可信性計算方法主要是聚合直接交互經(jīng)驗和第三方推薦經(jīng)驗來衡量Web服務(wù)的可信性,然而目前尚缺乏一個能夠較好的融合兩方面經(jīng)驗的方法。同時,也難以對Web服務(wù)可信度的變化做出實時的響應(yīng)。 針對上述問題,本文提出了一個基于協(xié)作頻度聚類的語義Web服務(wù)可信度計算方法。本文的主要工作和成果如下： 1.構(gòu)建語義Web服務(wù)的可信本體 在總結(jié)傳統(tǒng)軟件可信性的基礎(chǔ)上,對Web服務(wù)領(lǐng)域的可信領(lǐng)域進行了初步的研究,對可信屬性和屬性間的關(guān)系進行了概括和總結(jié),構(gòu)建了一個語義Web服務(wù)的可信性指標體系。在此基礎(chǔ)上,利用OWL本體描述語言構(gòu)建了一個可信本體,并對OWL-S進行擴展,使其支持Web服務(wù)的可信性描述。 2.提出了一種基于協(xié)作頻度聚類的語義Web服務(wù)可信度計算方法 本文提出了一種基于Web服務(wù)聚類的可信度計算方法。該方法利用Web服務(wù)間的協(xié)作關(guān)系對Web服務(wù)進行聚類,以此劃分Web服務(wù)群體。接著,通過Web服務(wù)間的交互獲得Web服務(wù)的個體可信度,并以Web服務(wù)群體為單位計算其群體可信度度,最后將Web服務(wù)的群體可信度與個體可信度聚合,得到一個綜合可信度。 3.設(shè)計了一種語義Web服務(wù)可信度計算框架SWSTE-C 針對本文提出的可信度計算方法,本文設(shè)計了一種語義Web服務(wù)可信度計算框架SWSTE-C。該框架以SOA架構(gòu)的三方角色為基礎(chǔ),對Web服務(wù)的協(xié)作記錄和信任關(guān)系進行管理,能夠支持Web服務(wù)的可信度計算,同時能對Web服務(wù)可信性的實時變化作出反
[Abstract]:As the main form of network, the credibility of Web services has become the main obstacle to the further development of Web services. However, the existing Web services technology does not have a complete and effective credibility description language, which makes it difficult for Web service providers and requesters to express their credibility demands. In addition, the existing credibility calculation methods are mainly to aggregate direct interaction experience and third-party recommendation experience to measure the credibility of Web services. However, there is still a lack of a better way to integrate the two aspects of experience. At the same time, it is difficult to respond to the change of Web service credibility in real time. To solve the above problems, this paper proposes a method for calculating the reliability of semantic Web services based on cooperative frequency clustering. The main work and results of this paper are as follows: 1. Constructing trusted Ontology of semantic Web Services On the basis of summarizing the credibility of traditional software, this paper makes a preliminary study on the trusted domain in the field of Web services, generalizes and summarizes the relationship between trusted attributes and attributes, and constructs a credibility index system of semantic Web services. On this basis, a trusted ontology is constructed by using OWL ontology description language, and OWL-S is extended to support the creditability description of Web services. 2. In this paper, a method for computing the reliability of semantic Web services based on cooperative frequency clustering is proposed. In this paper, a method of reliability calculation based on Web services clustering is proposed. This method uses the cooperative relationship between Web services to cluster Web services to divide the Web services population. Then, the individual reliability of Web service is obtained by the interaction between Web services, and the group reliability degree of Web service group is calculated in unit. Finally, the group reliability of Web service is aggregated with individual credibility, and a comprehensive credibility is obtained. 3. In this paper, a semantic Web service reliability computing framework, SWSTE-C, is designed. Aiming at the reliability calculation method proposed in this paper, a semantic Web service credibility computing framework SWSTE-C is designed in this paper. Based on the tripartite role of SOA architecture, the framework manages the cooperative record and trust relationship of Web services, which can support the credibility calculation of Web services and counter the real-time changes of Web services' credibility.
