基于网站结构的网络使用挖掘树化模型

A Tree Model for Web-Usage Mining Based on Web Site Structure

根据网站的树形结构特点,提出了一种统一的树化模型对用户访问路径进行建模,解决了因使用原始访问路径产生的"过度比较问题",并通过采用适合该模型的网页相对位置的概念,大大减轻了原来由于使用网页绝对访问位置导致的误差。结果表明:树化模型能够提高用户访问行为的相似度识别率。

In this paper, we abstract the salient features of the sequence as a tree model for web usage analysis, motivated by web site structure, to solve these problems. At the same time, we suggest the relative position to improve the error from the comparison of the absolutely position. Finally, the experimental results with an amount of datasets demonstrate the effectiveness of tree modeling approach.
