Defeasible Logic Programming (DeLP) is a knowledge representation formalism that combines results from Logic Programming and Defeasible Argumentation to provide reasoning based on contradictory and potentially incomplete information. DeLP allows information representation by using weak rules and provides an argumentation…

A new impetus for recollecting information seems regaining appeal, maybe heir of the “social indicators movement”. The movement was an heir to the supporters of quantification in the Social Sciences, as numbers were believed to be objective and scientific per…

A fuzzy controller is usually designed by formulating the knowledge of a human expert into a set of linguistic variables and fuzzy rules. As it is well known, the use of prior knowledge can dramatically improve the performance and quality…

El objetivo de este trabajo es estudiar los signos y profecías de Eneida lII entendidos como medio de comunicación del fatum entre dioses y hombres y, en consecuencia, inscriptos en el arte de la divinatio. Se analizan los anuncios de…

Las distintas cuestiones vinculadas al traspaso de las tierras públicas a manos particulares (en usufructo y en propiedad plena) en la campaña bonaerense del siglo XIX han suscitado el interés de diversos investigadores que, a partir de estudios de casos…

DLP is a basic java-based IDE specifically conceived for DeLP, that allows to compile DeLP programs and queries into JAM opcodes, execute those opcodes, and even witness the actual step by step construction of the dialectical tree that is built…

This paper addresses the problem of contour line extraction from scanned topographic maps in poor condition. A novel method is developed, using knowledge of cartography and graphics to extract contours by removing other layers which overlay the contours, and reconstructing…

Teachers must be able to adapt to a rapidly changing IT knowledge and technology. This requirement is further compounded by the need that this knowledge and technology be incorporated in the curriculum at the same rate.
This paper presents a…

The problem of speeding up ínference has proved to be important in argumentative systems. When computing dialectical structures, several paths are searched (called argumentation lines), many of which will eventually prove useless. Morover, the performance of backward chainers degrades quickly…
