恐怖袭击事件不确定性度量及可视分析
Uncertainty Measurement and Visual Analysis on Terroristic Attacks Data
摘要
Abstract
In recent years,terroristic activities occur more frequently and have seriously affected the regional stability and the world peace. With the development of information technology, the researchers are able to obtain information of terroristic attacks from many aspects. However, with the constant enlargement of the scale of data sets,how to explore the underlying information and analyze the uncertainty from a large number of data has become an important issue in the analysis process of terroristic attacks. On Global Terrorism Database,based on visual analysis and uncertainty measurement theory,we propose the measurement and visual analysis methods on data records and uncertainty of attributes. By integrating results of uncertainty measurement with parallel coordinates, histogram, area chart and interactive methods,the data uncertainty is clearly displayed without influence on its representation and provides information base for situation assessment based on uncertainty theory the next step.关键词
