Abstract

This paper presents a methodological approach to the management of symbolic preferences in integration with classical pure logical reasoning problems. We investigate two selection modes for choosing preferred sets of assumptions: democratism and elitism.

Principally we show how to manage the optimization of democratism preference criterion in the context of coherence restoration.

The use of symbolic structures for the preferences also makes possible the translation by formal duality of democratism preference-based coherence problems into elitism preference-based explanation problems.

Finally we insist on the computational aspects by considering the pragmatics of the integration problems and proposing constructive solutions.
