【摘要】:應(yīng)用偏好進(jìn)行服務(wù)選擇是Web領(lǐng)域的重要研究方向.在偏好研究中,偏好信息的獲得是一個(gè)復(fù)雜的過(guò)程,特別是獲取的過(guò)程涉及到普通的非專家用戶.獲取的偏好經(jīng)常會(huì)遇到偏好不完整、偏好沖突的問(wèn)題,在實(shí)際應(yīng)用中帶來(lái)很多的問(wèn)題.文中以條件偏好表示工具CP-net建模用戶的偏好,總結(jié)了CP-net中出現(xiàn)的不確定性,定義了偏好不完整、偏好沖突.提出了CP-net對(duì)應(yīng)的結(jié)果集合上的最優(yōu)關(guān)系與弱化的最優(yōu)關(guān)系.通過(guò)CP-net與對(duì)應(yīng)最優(yōu)關(guān)系的分析,提出了CP-net交運(yùn)算.在此基礎(chǔ)上,提出了解決CP-net中不確定問(wèn)題的方法,并對(duì)這個(gè)方法進(jìn)行了優(yōu)化.最后的實(shí)驗(yàn)證明了文中所提出方法的正確性和有效性.
[Abstract]:Application preference for service selection is an important research direction in the field of Web. In the research of preference, the acquisition of preference information is a complicated process, especially the process of obtaining information involves ordinary non-expert users. The obtained preference often encounters the problem of incomplete preference and preference conflict, which brings a lot of problems in practical application. In this paper, the conditional preference representation tool CP-net is used to model user preferences, and the uncertainties in CP-net are summarized, and the incomplete preferences and preference conflicts are defined. The optimal relation and the weakening optimal relation on the result set corresponding to CP-net are proposed. Based on the analysis of CP-net and corresponding optimal relation, CP-net intersection operation is proposed. On this basis, a method to solve the uncertainty problem in CP-net is proposed and optimized. Finally, the experimental results show that the proposed method is correct and effective.
