Abstract :
The combination and decomposition of database are two important problems in knowledge discovery and data mining, and their mathematic model are the combination and decomposition of information tables. In this paper, by giving the definitions of object-combined formal contexts and attribute-combined formal contexts, we discuss the relationship of attribute characteristic between object-combined formal contexts and the original formal contexts, attribute-combined formal contexts and the original formal contexts, respectively.
