Turning structured data into formal concepts.

My research field is Formal Concept Analysis: a mathematical way of discovering which objects share which attributes, and of ordering those groupings into a hierarchy called a concept lattice.

The field belongs to the symbolic tradition of AI. Every concept in the lattice is derived from the data, and nothing appears in the output that the input does not support. That guarantee is unfashionable, and generative AI cannot offer one.
