General Concept Lattice
The General Concept Lattice (GCL) proposes a novel general construction of concept hierarchy from formal context, where the conventional Formal Concept Lattice based on Formal concept analysis, Formal Concept Analysis (FCA) only serves as a substructure. The formal context is a data table of Binary relation, heterogeneous relations illustrating how objects carrying attributes. By analogy with Truth table, truth-value table, every formal context can develop its fully extended version including all the columns corresponding to attributes constructed, by means of Boolean operations, out of the given attribute set. The GCL is based on the ''extended'' formal context which comprehends the full information content of formal context in the sense that it incorporates whatever the formal context should consistently imply. Noteworthily, different formal contexts may give rise to the same extended formal context. Background The GCL claims to take into account the extended formal context ...
