Local-as-view integration of ontologies in defeasible logic programming
Gómez, Sergio Alejandro - Chesñevar, Carlos Iván - Simari, Guillermo Ricardo

Formato:	Objeto de conferencia, Objeto de conferencia
Enlaces:	Ontology integration is the problem of combining data sources in the SemanticWeb. Concepts in source ontologies are captured in terms of concepts de ned in a global ontology. When some of these ontologies are inconsistent, the knowledge engineer often has…

Analyzing the defeat relation in observation-based defeasible logic programming
Capobianco, Marcela - Chesñevar, Carlos Iván - Simari, Guillermo Ricardo

Formato:	Objeto de conferencia, Objeto de conferencia
Enlaces:	In the last decade several ways to formalize defeasible reasoning have been studied. A particular approach, defeasible argumentation, has been particularly successful to achieve this goal. The inference process of argument-based systems is based on the interaction of ar- guments…

Negation-as-failure considered harmful
Fillottrani, Pablo Rubén

Formato:	Objeto de conferencia, Objeto de conferencia
Enlaces:	In logic programs, negation-as-failure has been used both for representing negative information and for providing default nonmonotonic inference. In this paper we argue that this twofold role is not only unnecessary for the expressiveness of the language, but it also…
