摘要: 在国内外首次研究分形与概念格这两大领域之间的联系,提出了一种形式背景序列,这个形式背景序列将对应一个单位正方形中的图形序列,而这个图形序列的极限是一个分形图形。给出了分形背景序列的形式化表示方法,研究了这种分形背景序列的概念格序列的计算方法。证明了这个分形背景序列的极限概念格中的概念个数具有Hausdorff特性;对相应的极限图形定义了一个全新的维数:概念分数维,展示了两大领域联系的更多数据表征。

关键词: 分形, 概念格, 分形背景序列, 分数维, 概念分数维

Abstract: The association of fractal and concept lattice is firstly proposed in both domestic and international, a series of formal context is proposed which is corresponding to a graphic series of unit of square. The limitation of these graphic series is a fractal graph. The formalize method of representing fractal context is provided. Concept lattice series computing method of the fractal context series is researched too. It is proved that the number of concept in the concept lattice, which is the limitation of the fractal context series, has Hausdorff property, and then a new dimension is proposed for the graph of the limitation: Concept fraction dimension, which is used to show the more data catachrestic of the associations of the two big academic domains.

Key words: fractal, concept lattice, context series, fractal dimension, concept fractal dimension
