In traditional formal concept analysis, the attributes in the formal context are considered
fixed. However, in the real world data set, attributes always have different levels of …

In the formal concept analysis (FCA), a concept lattice represents the basic structure derived
from Boolean data describing the relationships between objects and attributes. One of the …
