横向合成背景的面向对象概念格的生成

摘要

Towards generation of concept lattice of multi formal context ,presents a generating method of object oriented concept lattice of multi context transverse synthesis. At first ,utilizes every concept′s ex⁃tension of each sub formal context ,through operation ,obtains the extension set of object oriented con⁃cept lattice of synthetic context. Then obtains the connotation of synthetic context through approximate op⁃erator operation to extension set ,and further obtains the concept lattice of synthetic context. The validity and completeness of this method are proved and the experiment results show that this method improves the time efficiency.%针对多形式背景合成的概念格生成，提出了一种多背景横向合成的面向对象概念格的生成方法。首先利用各个子形式背景中的每个概念的外延通过相关运算得到合成背景的面向对象概念格的外延集，然后将得到的外延集通过近似算子运算得到合成背景的内涵，并进一步得到合成背景的概念格。用理论证明该方法的有效性和完备性，并通过实验表明该方法时间效率较好。
