摘要： Wiki被广泛应用于协同工作环境，能实现用户的协同写作，但由于Wiki页面间导航的缺失，使用户很难找到目标页面。为此，使用协同过滤技术，通过对用户历史行为的分析，建立页面之间的关联，实现页面推荐系统。该系统使用基于用户行为的隐性评分，解决了Wiki中显性评分缺失的问题，并针对Wiki中用户关系随时间变化的特点，设计基于关联规则的相似度函数。应用结果表明，该系统能帮助用户快速找到目标页面，提高用户的浏览效率。

Abstract: Wiki based collaboration platforms are used broadly, which brings a great of flexibility and effectiveness. However the lack of navigation supporting in Wiki makes it hard for user to find target page. By using collaboration filtering technical, this paper implements a page recommendation system to build the connection of pages. The absence of explicit rating in Wiki is solved by using implicit rating extracting from user history behavior. For the relation of users is time related, a new similarity function is proposed. Application result shows that the page recommendation system enhances the user browsing experience in Wiki, and helps user find target page effectively.

Key words: collaborative filtering, page recommendation, implicit rating, collaborative working environment, association rule
