The Bactra Review   Induction
The notion of ``concept'' our authors use here is extremely close to that employed by the philosopher of science Stephen Toulmin in Human Understanding: The Collective Use and Evolution of Concepts (Princeton U.P., 1972), which however our authors do not cite. Toulmin thought of his concepts as an alternative to formalization via logic or AI, so it's amusing to see them get perfectly good computational implementations; but also reassuring to me, since his arguments on their behalf make a lot of sense.
