The incremental algorithm introduced in (Dale and Reiter, 1995) for producing dis- tinguishing descriptions does not always generate a minimal description. In this paper, I show that when generalised to sets of individuals and disjunctive proper- ties, this approach might generate unnec- essarily long and ambiguous and/or epis- temically redundant descriptions. I then present an alternative, constraint-based al- gorithm and show that it builds on existing related algorithms in that (i) it produces minimal descriptions for sets of individu- als using positive, negative and disjunctive properties, (ii) it straightforwardly gener- alises to n-ary relations and (iii) it is inte- grated with surface realisation.
