足球动态传球网络的可视化

Toward Better Understanding of Dynamic Soccer Passing Networks

足球传球网络分析对提高球队的进攻效率起着重要作用.然而,大多数现有工作都将传球网络视为静态网络,忽略了比赛过程中传球的时空演变.该工作通过与领域专家的深入访谈总结了动态传球网络分析的重要任务,并提出了一个交互式可视分析系统支持对传球网络的时空动态性进行全面分析.该系统应用了基于图标的可视化方法和投影技术,以呈现不同时间下的传球网络拓扑结构和传球空间上下文信息.该系统可以辅助用户发现传球网络结构和传球所在的空间位置在时间上的变化模式以及两者之间的关联,并根据传球网络动态性对比赛过程进行更深入的解读,发现有价值的传球网络变化策略.通过案例分析和专家访谈,验证了该系统在分析传球网络动态性的可用性和有效性.

Recent studies have confirmed that analysis of passing networks of soccer can provide insights for un-derstanding teams’attacking strategies.However,most of the existing works regarded passing networks as static networks,failing to investigate the change of strategies and time-varying passing patterns.To address the prob-lem,important tasks from interviews with domain experts are identified and an interactive visual analytics system is developed to support comprehensive analysis of the dynamics of passing networks.A glyph-based design ac-companied with projection techniques is proposed to visualize the dynamic change in network topologies,the as-sociated spatial context,and the network characteristics.With the system,users can detect the changing pattern of passes and analyze the relationship between passes and spatial regions.For evaluation,expert interviews are conducted to demonstrate the usability of the system in analyzing the dynamics of passing networks.
