概念格是形式概念分析中的核心数据结构,概念格应用的瓶颈之一是其构造效率. 针对形式背景的某个属性分解为多个新属性得到更加特化的概念,给出了一种基于概念特化的渐进式更新构造算法. 该算法利用分解后的新属性及其相应的形式背景,构造出的概念格与原概念格的某个子概念格作比较,来更新构造概念格,从而减少了比较次数,提高了更新构造的效率. 以天体光谱数据作为形式背景,实验验证了该算法的正确性和有效性.

Concep t lattices are the core data structures in formal concep t analysis. The widesp read app lication of con2 cep t analysis is limited by the difficulty of constructing a concep t lattice. An incrementally updating construction algo2 rithm based on concep t spcializationwas developed after itwas realized that the attributes in the formal context can be decomposed into several new attributes, ormore specialized concep ts. The algorithm, with decomposed attributes and a corresponding formal context, compares the concep t lattice formed with the new attributes and one of the sub2lattices of the original concep t lattice, then upgrades the concep t lattice according to results from the comparisons. In this way the number of comparisons is reduced and the efficiency of constructing the concep t lattice is imp roved. Experi2 ment results, with celestial spectrum data as the formal context, verified the validity of the algorithm
