Variable−Strength Conditional Preferences for Ranking Objects in Ontologies

Abstract:

We introduce conditional preference bases as a means for ranking objects in ontologies. Conditional preference bases consist of a description logic knowledge base and a finite set of variable-strength conditional preferences. They are inspired by Goldszmidt and Pearl's approach to default reasoning from conditional knowledge bases in System Z+. We define a notion of consistency for conditional preference bases, and show how consistent conditional preference bases can be used for ranking ob...
