| 摘 要： | 介绍传统协同过滤方法，提出一个新的基于情景的多维协同过滤推荐模型。在该模型中，介绍情景的概念；阐述建立基于情景的多维用户模型的方法，并对基于情景的多维协同过滤推荐模型的组成部分进行详细介绍。提出一种计算情景相似度的新算法。基于该新算法，可以得到当前用户的“最近邻”在当前用户所在情景下对项目的评分。

| Abstract: | A novel collaborative filtering method to take contextual information into consideration is proposed.A context-based multidimensional collaborative filtering recommendation model is presented and the parts of the model are disscussed in detail.A new algorithm to figure out the similarities between the previous contexts and the current context of the active user is described,and a new equation to get the context-based ratings of the nearest neighbors of the active user is designed.And then the ultimate ratin... |
