Attribute exploration,theory. The canonical basis generates the implication theory of these five attributes for . triangles. Every implication that holds for all triangles follows from the canonical basis. For every implication that does not hold in general, there is already a counterexample among the seven triangles of the formal context.

The third section is devoted to ., which was already mentioned in the very first publication on Formal Concept Analysis. Three more generalizations are sketched in the fourth section, which then concludes by mentioning a few further ones.

Concept lattices,offers several highly practical methods for working with concrete qualitative data. A solid knowledge of FCA is not a prerequisite for attribute exploration, but knowing the basic ideas will help. We therefore start with an introduction.

The canonical basis,each other. Each of the ten objects is a pair of unit squares representing a possible placement. These ten pairs are representatives for an infinite set of possible positions that such pairs of squares may have. It is not stated, but perhaps expected by the reader, that these ten examples cover all

This information is important, because it shows that the concept lattice given in Figure 1.16 (p. 27) will not change if more examples are added. The triangles in the formal context are representative of the entire

We start with ., which lifts attribute exploration in a rather naturalway to first-order predicate logic, with Horn formulas replacing implications. Next we discuss how attribute exploration can be integrated with .. However, so much subs
