A priori indexing systems for case-based reasoning are unlikely to engender interesting, let alone creative, explorations. The problem is that they assume a predetermined knowledge and conceptual structure which neglect new and emergent relations. By allowing multiple labelling of entities, it can be shown that different orders of emergent relations can be derived on the fly without any conventional classification schemes. This gives a flexible, scalable, and most importantly, an associative reasoning system that is more likely to trigger interesting concepts which are technically “categorical errorsi but seeds of creative thought.
