A Tractable First-Order Probabilistic Logic
Tractable subsets of first-order logic are a central topic in AI research. Several of these formalisms have been used as the basis for first-order probabilistic languages. Howev...

Default logic generalized and simplified
We provide a description of generalized default logic as a unified formalism for nonmonotonic reasoning. Special attention will be paid to the role of the monotonic logic underlyi...

The Representation of Defaults in Cyc
This paper provides an account of the representation of defaults in Cyc and their semantics in terms of first order logic with reification. Default reasoning is a complex thing, a...

Conditional Logics of Normality as Modal Systems
Recently, conditional logics have been developed for application to problems in default reasoning. We present a uniform framework for the development and investigation of conditio...

Statistical Foundations for Default Reasoning
We describe a new approach to default reasoning, based on a principle of indi erence among possible worlds. We interpret default rules as extreme statistical statements, thus obta...

Towards an Axiom System for Default Logic
Recently, Lakemeyer and Levesque proposed a logic of onlyknowing which precisely captures three forms of nonmonotonic reasoning: Moore's Autoepistemic Logic, Konolige's ...

Fred meets Tweety
We propose a framework that brings together two major forms of default reasoning in Artificial Intelligence: applying default property classification rules in static domains, and d...

Preference-Based Default Reasoning
It is well-known that default reasoning and preference-based decision making both make use of preferential relations between possible worlds resp. alternatives. In this paper, we ...

Presuppositions and Default Reasoning: A Study in Lexical Pragmatics
Explaining how the meaning of words relate to the meaning of the utterance in which they are used is of utmost importance. The most common approaches view the meaning of an uttera...

What the Lottery Paradox Tells Us About Default Reasoning
In this paper I argue that we do not understand the process of default reasoning. A number of examples are given which serve to distinguish di erent default reasoning systems. It ...
