摘要: 针对传统关联规则可视化方法无法展现数据间的频繁模式和关联关系,表示形式比较单一,缺乏多模式展现形式等问题,提出了一种新的多值属性关联规则可视化表示算法。该算法运用概念格理论对多值属性数据进行了重新定义和分类,将频繁项集和关联规则中的多值数据项分别以概念格结构进行表示,实现了频繁项集可视化展示和一对一、一对多、多对一、多对多及概念分层的多模式关联规则可视化展示。最后,以某省全员人口数据为基础对算法进行了具体实现和分析,同时实现了对人口数据的源数据、频繁模式以及关联关系的可视化展示。实验结果表明,所提出的可视化形式和已有成果相比具有良好的频繁项集与多模式关联规则展现效果。

Abstract: Considering the problems caused by the traditional association rules visualization approaches, including being unable to display the frequent pattern and relationships of items, unitary express, especially being not conducive to represent multi-schema association rules, a new visualizing algorithm for multi-valued association rules mining was proposed. It introduced the redefinition and classification of multi-valued attribute data by using conceptual lattice and presented the multi-valued attribute items of frequent itemset and association rules with concept lattice structure. This methodology was able to achieve frequent itemset visualization and multi-schema visualization of association rules, including the type of one to one, one to many, many to one, many to many and concept hierarchy. At last, the advantages of these new methods were illustrated with the help of experimental data obtained from demographic data of a province, and the source data visualization, frequent pattern and association relation visual representation of the demographic data were also achieved. The practical application analysis and experimental results prove that the schema has more excellent visual effects for frequent itemset display and authentical multi-schema association rules visualization.
