C-logic of complex objects

Abstract

Our objective is to have a logical framework for natural representation and manipulation of complex objects. We start with an analysis of semantic modeling of complex objects, and attempt to understand what are the fundamental aspects which need to be captured. A logic, called C-logic, is then presented which provides direct support for what we believe to be basic features of complex objects, including object identity, multi-valued labels and a dynamic notion of types. C-logic has a simple first-order semantics, but it also allows natural specification of complex objects and gives us a framework for exploring efficient logic deduction over complex objects.
