Inheritance is often portrayed as a fundamental ingredient of object-oriented programming, one which is essential to building extensible software systems. However, inheritance is also a controversial mechanism with many competing and often contradictory interpretations, whose use can even impede extensibility in certain scenarios. Decomposing inheritance into the more basic mechanisms of object...

In this paper we develop a method for clustering all types of belief functions, in particular nonconsonant belief functions. Such clustering is done when the belief functions concern multiple events, and all belief functions are mixed up. Clustering is performed by decomposing all belief functions into simple support and inverse simple support functions that are clustered based on their pairwis...
