In order to solve the problem that current search engines provide query - oriented searches rather than user - oriented ones, and that this improper orientation leads to the search engines ' inability to meet the personalized requirements of users, a novel method based on probabilistic latent semantic analysis ( plsa ) is proposed to convert query - oriented web search to user - oriented web search. first, a user profile represented as a user ' s topics of interest vector is created by analyzing the user ' s click through data based on plsa, then the user ' s queries are mapped into categories based on the user ' s preferences, and finally the result list is re - ranked according to the user ' s interests based on the new proposed method named user - oriented pagerank ( uopr ). experiments on real life datasets show that the user - oriented search system that adopts plsa takes considerable consideration of user preferences and better satisfies a user ' s personalized information needs
針對當前的搜索引擎提供面向查詢、而非面向用戶的服務，從而導致搜索引擎無法滿足用戶個性化的需求這一問題，提出了一種基於plsa的新方法，將面向查詢詞的搜索轉變成面向用戶的搜索.首先，通過分析用戶查詢歷史和瀏覽記錄建立代表用戶模型的用戶興趣向量，在用戶發出查詢時用戶的查詢詞根據用戶興趣向量被映射到興趣分類上，最終根據面向用戶排序演算法將返回結果列表重新排序.實驗表明該面向用戶搜索系統能夠充分考慮用戶的偏好，從而更好地滿足不同用戶的信息需求
