提出了一种利用电子书系统采集的点击流数据进行变化检测的新方法。以前的大部分工作都集中在点击流数据的批处理上。相反,该方法是为在线处理而设计的,根据对新点击事件的观察,顺序地更新用于变化检测的模型参数。更具体地说,我们的方法为单个学生生成一个模型,并根据课堂讲课期间的点击事件执行每分钟的变化检测。我们收集了四个面对面讲座的点击流数据,并进行了实验,展示了所提出的方法是如何发现变化点的,以及这些变化点与学生的表现是如何关联的。
We propose a new change detection method using clickstream data collected through an e-Book system. Most of the prior work has focused on the batch processing of clickstream data. In contrast, the proposed method is designed for online processing, with the model parameters for change detection updated sequentially based on observations of new click events. More specifically, our method generates a model for an individual student and performs minute-by-minute change detection based on click events during a classroom lecture. We collected clickstream data from four face-to-face lectures, and conducted experiments to demonstrate how the proposed method discovered change points and how such change points correlated with the students' performances.
