On the Parameterized Complexity of Default Logic and Autoepistemic Logic
We investigate the application of Courcelle’s Theorem and the logspace version of Elberfeld et al. in the context of the implication problem for propositional sets of formulae, t...

dl2asp: Implementing Default Logic via Answer Set Programming
In this paper, we show that Reiter’s default logic in the propositional case can be translated into answer set programming by identifying the internal relationships among formula...

An Interpretation of Default Logic in Minimal Temporal Epistemic Logic
When reasoning about complex domains, where information available is usually only partial, nonmonotonic reasoning can be an important tool. One of the formalisms introduced in thi...

Alternative foundations for Reiter's default logic
We introduce an alternative conceptual basis for default reasoning in Reiter's default logic. In fact, most formal or computational treatments of default logic suffer from th...

Reasoning with Sets of Defaults in Default Logic
We present a general approach for representing and reasoning with sets of defaults in default logic, focussing on reasoning about preferences among sets of defaults. First, we con...

Splitting a Default Theory
This paper presents mathematical results that can sometimes be used to simplify the task of reasoning about a default theory, by \splitting it into parts." These so-called Sp...

Compiling Reasoning with and about Preferences into Default Logic
We address the problem of introducing preferences into default logic. Two approaches are given, one a generalisation of the other. In the first approach, an ordered default theory...

Use of Default Reasoning for Disambiguation Under Question Answering
We develop the default logic for pragmatic analysis of natural language queries. Ambiguous sentences are considered so that each set of meanings is assigned an extension of defaul...

Handling Exceptions in nonmonotonic reasoning
Abstract We introduce some differences in the style defeasible information is represented and inferences are made in nonmonotonic reasoning. These, at first sight harmless, chang...

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...
