使用多维缩放的动态扩展来动画化社交网络随时间的发展

Animating the development of Social Networks over time using a dynamic extension of multidimensional scaling

Loet Leydesdorff, Thomas Schank, Andrea Scharnhorst, Wouter De Nooy

摘要:

网络可视化的动画带来了技术和理论上的挑战。在心理地图使用户能够随着时间的推移进行推断之前,需要相当稳定的模式。为了提高稳定性,我们开发了一个扩展的应力最小化随着时间的推移的发展。这种动态布局不再基于独立静态可视化之间的线性插值,而是将随时间的变化用作优化中的参数。由于我们的重点是结构变化与稳定性的注意力从关系图转移到矩阵的潜在特征向量。该方法是用动画说明的期刊引用环境的社交网络,(共同)作者网络在该杂志的承载社区,和主题的发展使用的标题词之间的关系。我们的研究结果也进行了比较,基于PajekToSVGAnim和SoNIA的动画。

英文摘要:

The animation of network visualizations poses technical and theoretical challenges. Rather stable patterns are required before the mental map enables a user to make inferences over time. In order to enhance stability, we developed an extension of stress-minimization with developments over time. This dynamic layouter is no longer based on linear interpolation between independent static visualizations, but change over time is used as a parameter in the optimization. Because of our focus on structural change versus stability the attention is shifted from the relational graph to the latent eigenvectors of matrices. The approach is illustrated with animations for the journal citation environments of Social Networks, the (co-)author networks in the carrying community of this journal, and the topical development using relations among its title words. Our results are also compared with animations based on PajekToSVGAnim and SoNIA.
