基于属性偏序结构图的文本型灾情多元信息可视化
Textual Disaster Multivariate Information Visualization based on Attribute Partial Orderstructure Diagram
摘要
Abstract
An hierarchy of traditional concept lattice is not clear in processing and analyzing multivariate in-formation about textual disaster.This is not conducive to carry on data mining and knowledge discovery to support decision making.It is proposed that the representation method of attribute partial order structure diagram by apply-ing the ranks exchange principle of formal context to optimize formal context.The method has advantage in analy-zing some concepts and hierarchical attribute clustering.It can realize knowledge discovery,hierarchical informa-tion visualization and information fusion of huge amounts of multivariate data.The method was applied to draw mul-tiple attribute partial order structure diagrams of the national crop disaster and inundated area during 1995 -1999. The results show that this approach is clear,intuitive,and supportiveto information analysis and trend judgment of textual disaster information.关键词
