A Defeasible Logic of Policy-Based Intention
Most of the theories on formalising intention interpret it as a unary modal operator in Kripkean semantics, which gives it a monotonic look. We argue that policy-based intentions [...

An algorithm for the induction of defeasible logic theories from databases
Defeasible logic is a non-monotonic logic with applications in rule-based domains such as law. To ease the development and improve the accuracy of expert systems based on defeasib...

Induction of Defeasible Logic Theories in the Legal Domain
Defeasible Logic is a promising representation for legal knowledge that appears to overcome many of the deficiencies of previous approaches to representing legal knowledge. Unfor...

Defeasible Description Logics
We propose to extend description logic with defeasible rules, and to use the inferential mechanism of defeasible logic to reason with description logic constructors.

A Defeasible Logic Reasoner for the Semantic Web
Abstract. Defeasible reasoning is a rule-based approach for efficient reasoning with incomplete and inconsistent information. Such reasoning is, among others, useful for ontology i...

Extending Defeasible Logic and Defeasible Prolog
Abstract. Defeasible logic (DL) promotes enthymemic, argumentative reasoning on incomplete set of premisses retracted on the presence of contrary information. Defeasible Prolog (d-...

Nested Rules in Defeasible Logic
Defeasible Logic is a rule-based non-monotonic logic with tractable reasoning services. In this paper we extend Defeasible Logic with nested rules. We consider a new Defeasible Log...

A Semantic Web Based Architecture for e-Contracts in Defeasible Logic
Abstract. We introduce the DR-CONTRACT architecture to represent and reason on e-Contracts. The architecture extends the DR-device architecture by a deontic defeasible logic of vio...
