摘要: 时序数据是数据挖掘的一类重要研究对象,当前的时序数据可视分析技术很少进行跨域关联,用户无法在统一视图中同时关注时空域的统计时序数据与认知域的文本主题数据的发展演化。抽象出用户基于跨域时序数据的可视分析过程,提出一种可视分析流程模型;以该模型为指导,设计了多视图协同的跨域关联可视分析工具。通过疫情时序数据和舆情文本数据的实例分析,证明了本方法可以较好的支撑用户同时关注不同域时序数据的发展演化,快速探索数据中隐含的特征信息和时空变化规律。

关键词: 时序数据, 文本主题数据, 时空域, 认知域, 跨域关联, 可视分析

Abstract: Time series data is the important research object of data mining. The current visual analysis technology of time series data rarely conducts the cross-domain correlation. The development and evolution of statistical time series data in the spatio-temporal domain and the text theme data in the cognitive domain cannot be simulitaneously supervised in a unified view. The user's visual analysis process based on cross-domain time series data is abstracted and a visual analysis process model is proposed. A multi-view collaborative cross-domain correlation visual analysis tool is designed on the basis of the model. The case study of epidemic time series data and public opinion text data show that the method can well support users to supervise the development and evolution of the time series data in different domain at the same time, and quickly explore the characteristic information and temporal and spatial changes of the data.

Key words: time series data, text theme data, spatio-temporal domain, cognitive domain, cross domain correlation, visual analytics
