e-Learning视域中知识可视化模型比较研究

A Comparison Study on Knowledge Visualization Model in the Field of e-Learning

With the widespread application of knowledge visualization tools， the research of knowledge visualization is becoming more and more deeply， and the related researchers put forward a more systematic knowledge visualization structure model. In this study， the existing typical knowledge visualization models will be compared and studied more deeply based on E-learning. The purpose of this study is to understand the process and method of visualization. It is found that the various knowledge visualization models are almost identical in their constituent elements and core processes， but there are differences in the three aspects of theoretical basis， the differences between the elements and interaction orientation. We study the interaction behavior of knowledge visualization， and adopt different knowledge visualization methods for different types of knowledge， which will become the focus of building knowledge visualization model. This study is of great significance for improving the basic theory of knowledge visualization and guiding the practice of knowledge visualization.
