针对Storyline可视化局部放大问题,提出一种基于内容重要性的局部变形框架.首先对可视化领域中局部变形技术进行对比和分析;然后给出了Storyline可视化可视元素及其重要性计算方法,并对重要性较大的实体元素进行放大显示,在高斯函数的指导下对重要会话元素进行局部放大和过渡平滑处理,根据不同位置的权重对线条进行重新定位;最后以Inception交互会话数据为实验数据,将该方法应用到Storyline可视化视图中.实验结果表明,文中方法能够在有限的显示空间中对Storyline可视化视图的整体结构和局部详细信息同时进行协调、友好的可视化.

英文摘要：

To solve the problem of partial enlargement of Storyline visualization view, a local deformation framework based upon the significance of content is proposed. The local deformation technologies widely used in the field of information visualization are compared and analyzed. Then the calculations for visual elements and their significance are described. And the entity elements with higher significance are enlarged. With the guidance of Gaussian function, the partial enlargement and smooth transition for the important inter-session elements are conducted. Lines are relocated according to the weight of their location. Finally, the method is applied to the Storyline visualization view using the experimental data of the movie Inception. Experimental results show that it is effective to coordinate the integral structure and partial detail information of Storyline visualization view.
