Determination and representation

How do you calculate the concept lattice and a good diagram for a given formal context? In principle, this is simple and can be done by hand.We introduce this in the first section of this chapter. However, the work becomes tedious very quickly, and computer assistance is desired. Since the introduction of Formal Concept Analysis, so many algorithms and implementations have emerged that we cannot discuss them here and instead refer to [154]. These computer programs are impressively fast. A concept lattice with a billion elements can easily be computed, and diagrams are also provided. However, computer-generated lattice diagrams are rarely satisfactory.
