In this work, we discuss aspects of a framework to support the understanding and the improvement in hypermedia development processes. The framework is built taking into account two modeling approaches and four domain levels. The modeling approaches are called prescriptive…

Se analizó el perfil de uso de los medicamentos utilizados en los pacientes adultos mayores (65 años o más) atendidos en los Centros de Salud, urbanos, de la Provincia de Santiago, Chile, durante los meses de junio a octubre de…

Como numerosos procesos biológicos, la proliferación de diversas poblaciones celulares animales presenta un ritmo circadiano. La respuesta diferencial a la ciclofosfamida ha sido relacionada con la periodicidad mitótica diaria en un carcinoma mamario de ratón. El presente trabajo analiza la…

La Creación del Centro Brasil fue consecuencia de la preocupaciín de los miembros del Departamento de América Latina y el caribe del IRI, por contar con un área especializada en el estudio de los principales aspectos sociales, políticos, legales y…

Frequently we become amazed with the increasing number of problems to be solved that fiourish while facing daily activities. Often, related to these problems we llave also an incredible amount oí data. Since we cannot allways afford time and resources…

The notion of context and its importance in knowledge representation and nonmonotonic reasoning was first discussed in Artificial Intelligence by John McCarthy.
Ever since, contexts have found many applications in developing knowledge-based reasoning systems.
Defeasible argumentation has gained wide acceptance…

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…

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 matrix connection method (MCM) is an alternative procedure for theorem proving than the usual resolution technique. We already have used the MCM for finding models in a real-time knowledge-based system generator. In this paper, we adapt the MCM to…
