Effective document retrieval using domain knowledge and semantics is one of the major challenges in Information Retrieval. Over the last years, there has been a growing interest in ontologies as an artifact for human knowledge representation and a critical component…

El objetivo de esta investigación es el estudio de la problemática de inconsistencia que pueda aparecer en los Sistemas Basados en Conocimiento (SBC). Los SBC pueden ser clientes de muchas fuentes de información, y estas pueden contener información inconsistente al…

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…

Un rasgo fundamental del nuevo modelo productivo que se consolidó en las últimas dos décadas es la centralidad que adquieren las capas empresariales. Este hecho encierra una serie de interrogantes en los que conviene detenerse, en tanto aluden al análisis…

Argumentative formalisms have been widely recognized as knowledge representation and reasoning tools able to deal with incomplete and potentially contradictory informa- tion. All such formalisms are computationally demanding. Hence, optimizing argumen- tative systems has been approached from di erent views.

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 ot…

Desde la filosofía de la inclusión social y el criterio de los Derechos Humanos, la educación inclusiva en la primera infancia es fundamental para los niños con discapacidades; la escuela suele ser el ámbito donde sus necesidades educativas se reconocen…

This paper presents a proposal for an architecture that integrates knowledge discovery systems (automatic acquisition) and knowledge based systems (experts systems). This work formulates considerations over the viability of the implementation of this architecture according to the advance of the…

The design of intelligent agents is a key issue for many applications. Since there is no universally accepted definition of intelligence, the notion of rational agency was proposed by Russell as an alternative for the characterization of intelligent agency.
A…

Most formalisms for representing common-sense knowledge allow incomplete and potentially inconsistent information. When strong negation is also allowed, contradictory conclusions can arise. A criterion for deciding between them is needed. The aim of this paper is to investigate an inherent…
