Current reasoning systems attempt to model an agent's knowledge and interaction with its environment in a symbolic manner. This environment, its world is generally dynamic and changing due to natural evolution or the actions of other agents that are a…

Artificial Intelligence has long dealt with the issue of finding a suitable formalization for reasoning with incomplete and potentially inconsistent information. Defeasible argumentation [SL92,CML00,PraVre99] has proven to be a successful approach in many respects, since it naturally resembles many aspects…

This paper summarizes the main results developed in the author's PhD Thesis.
The main goal of the Thesis is to provide a formalization of defeasible argumentation oriented towards its computational treatment. In order to do this, an LDS-based logical framework…

Se presentan ocho fechados 14C-AMS sobre colágeno de huesos craneanos sin alteración diagenética, provenientes de la cueva de Haichol, Neuquén, que serán discutidos con el propósito de adquirir conocimientos más precisos relativos a cronología, paleodieta, entorno paleoambiental del sitio y…

When certain enterprise domain needs to make an unusual decision, it will probably require new kind of information. If the interaction model among domains cannot be defined because the decision scenarios are unpredictable, the system itself must search the required…

This work extends the semantics and implementation of fuzzy prolog presented in [VGM02] in order to include Default Knowledge capability. The new semantic allows non-uniform default assumptions and has Closed World Assumption (CWA) and Open World Assumption (OWA) as particular…

En este trabajo se analizan los símbolos y representaciones del proceso de gestación entre los tobas de la provincia de Formosa poniendo especial énfasis en sus transformaciones e interrelaciones con las instituciones y representaciones biomédicas. Se considera el simbolismo del…

The proposal of this research line is the search for alternatives to the resolution of complex problems where human knowledge should be apprehended in a general fashion. In particular, the activities developed so far can be included in the area…

It is interesting and important to compare, analyze and assess the alternative tools that could be used in the area of Knowledge Representation. In this paper we present a reasearch line associated to this goal: to formally establish the relation…

El conocimiento de la composición biotípica de una población de áfidos es importante para poder
prevenir daños que se producirían en cultivares seleccionados por su resistencia al ataque de áfidos
de distintos tipos. Con el propósito de analizar la composición…
