| 摘 要： | 为使用户在手持设备上提取用户兴趣是重要基础,提出一种基于用户隐式反馈的方法。该方法从网页中提取兴趣块(用户感兴趣的网页内容),假设用户的浏览行为如在块上的停留时间、滚动次数、滚动速度、进入链接的次数等与用户是否对块感兴趣相关。从手持设备上的浏览行为中提取了34种隐式反馈特征,通过分析18个用户在608个网页的9474个块上的浏览行为,验证了其中29种特征与兴趣块的相关性,并且这种相关性能用于跨用户、跨网站的兴趣块提取。该文的研究成果可用于建立个性化的用户偏好模型,应用在手持设备上的自适应网页浏览中。

| Abstract: | Personalized web page adaptation on handheld devices is based on learning the user's interests.A method was developed to identify a user's interest blocks using implicit feedbacks extracted from the user's browsing behavior,such as display time,scrolling and link selection.34 kinds of block-based implicit feedbacks were extracted,29 of which prove to be statistically relevant to interest blocks through a user study with 18 participants who browsed 9 474 blocks on 608 pages.C4.4,SVM,and NaiveBayes methods we... |
