通过研究移动用户的访问行为特点，给出了情景和用户兴趣度的定义，提出了一种基于情景结合用户兴趣度的移动Web预取算法。依据Web日志数据计算移动用户在不同情景下的兴趣度，建立移动用户的情景相似度矩阵和兴趣度矩阵，通过这两个矩阵预取移动用户最感兴趣的N个页面同时计算预取的准确率。采用实例介绍了该算法的具体过程，验证了其有效性。
通過研究移動用戶的訪問行為特點，給齣瞭情景和用戶興趣度的定義，提齣瞭一種基于情景結閤用戶興趣度的移動Web預取算法。依據Web日誌數據計算移動用戶在不同情景下的興趣度，建立移動用戶的情景相似度矩陣和興趣度矩陣，通過這兩箇矩陣預取移動用戶最感興趣的N箇頁麵同時計算預取的準確率。採用實例介紹瞭該算法的具體過程，驗證瞭其有效性。

By studying the features of mobile user behavior,the definition of context and user interest degree was given and a prefetching algorithm based on context and user interest degree was proposed.In this algorithm,the user interest degree in dif-ferent context was calculated to build context similarity and interest matrix according to Web log data.Then the Top-N pages which mobile user were most interested in were prefetched and the prefetching precision was calculated.Finally,the algorithm was illustrated with a specific example.
