We provide a generalization of Formal Concept Analysis that works with different types of the values in a heterogeneous formal context. ...
An appropriate counterpart of the basic theorem on concept lattices is formulated. We suggest the transformation of the heterogeneous formal context to Galois connectional approach. ...
