This study investigates an approach of knowledge discovery and data mining in insufficient databases. An application of Computational Taxonomy analysis demonstrates that the approach is effective in such a data mining process. The approach is characterized by the use of…

The computational metaphor which proposes the comparison of processes of mind to realizable or imaginable computer activities suggests a number of educational concerns. This paper discusses some of those concerns including procedural modes of knowledge representation and control knowledge ??owing…

This paper deals with the "Calculus of Knowledge", an extension of the propositional calculus in which one may reason about what other people know. Semantic and Syntactic systems are developed, certain theorems are proven, and a formal solution in the…

Complex control tasks may be solved by dividing them into a more specific and more easily handled subtasks hierarchy. Several authors have demonstrated that the incremental layered evolution paradigm allows obtaining controllers capable of solving this type of tasks.
In…

Los cambios que afectan a las instituciones educativas universitarias ocurren en distintos órdenes y se refieren a: cambios en el conocimiento (en la generación, gestión y distribución del mismo); cambios socio-culturales (relacionados con la globalización); cambios propiciados por las TIC…

There are multiple sorts of reasoning by analogy between two domains; the one with which we are concerned is a type of contextual analogy. The purpose of this paper is to see whether two domains that look analogous would be…

Humans recognize optical reflectance properties of surfaces such as metal, plastic, or paper from a single image without knowledge of illumination. We develop a machine vision system to perform similar recognition tasks automatically. Reflectance estimation under unknown, arbitrary illumination proves…

The exponential increase of subjective, user-generated content since the birth of the Social Web, has led to the necessity of developing automatic text processing systems able to extract, process and present relevant knowledge. In this paper, we tackle the Opinion…

A lo largo de nuestros años de estudiantes nos prepararon para encontrar soluciones a los distintos problemas que encontramos dentro la vida cotidiana del ser humano. Notamos la falta de interés y no el poco sino nulo conocimiento de las…

Cette recherche témoigne d'une démarche de recherche-action-participative réalisée auprès d'enfants ayant vécu la perte d'un parent. Elle vise à comprendre l'expérience vécue par les enfants endeuillés d'un parent qui participent à un groupe d'intervention axé sur le modèle de l'aide…
