Computational and Structural Aspects of Openly Speciied Type Hierarchies

Abstract

One may identify two main approaches to the description of type hierarchies. In total speciication, a unique hierarchy is described. In open speciication, a set of constraints identiies properties of the hierarchy , without providing a complete description. Open speciication provides increased expressive power, but at the expense of considerable… (More)
