Towards a Preference Formalism for Modular Systems

摘要

We propose a framework for combining knowledge bases in modular systems with preferences. In our formalism, each module (knowledge base) may be characterized in a different language. Preferences defined over each module can be specified by different preference formalisms. We define the notion of a preference-based modular system that includes a formalization of meta-preferences. We prove that our formalism is robust in the sense that the operations for combining modules preserve the notion of a preference-based modular system.
