目的研究多形式背景横向合并前后属性特征的变化情况。方法概念格约简与属性分类理论。结果得到了形式背景的属性特征在横向合并前后的关系。结论多形式背景横向合并前后属性特征有着内在的联系,为进一步研究其属性约简之间的关系有重要意义。
Aim To study the change of attribute characteristic when some contexts are combined into one. Methods Using the theory of concept lattices reduction and attributes classification. Results The relations of attribute characteristic between the combined formal context and primary formal contexts were obtained. Conclusion There are inherent relations between attlibute characteristics of the csmbined formal context and that of plimery formal contexts, which has importont signicanle in ottlibute reduction theory.
