In this paper, we present an approach to student's evaluation in a well-defined domain based on a semantic network. A similarity matrix based on the semantic memory structure of humans is used to build a semantic distance model in order…

Over the last several years, multidimensional data modeling has had several proposals for its formalisation; on the other hand, the incorporation of fuzzy logic in databases has increased the need to represent uncertainty.
However, to our knowledge, so far projects…

Esta tesis presenta una estrategia en la Ingeniería de Requisitos, denominada SDRES, que intenta abordar temas poco tratados en la práctica real, tales como los cambios constantes en los requisitos, defectos del software originados en los requisitos, el contexto organizacional…

Las firmas agroindustriales exportadoras argentinas de productos en fresco están transitando por un proceso progresivo de modernización e implementación de normativas internacionales sobre calidad agroalimentaria.

En las investigaciones en Ciencias Geológicas, en nuestro país y en especial en la Provincia de Buenos Aires, ha sido escaso el desarrollo relacionado con los sitios que requieran una preservación y protección especial. Sin embargo, son abundantes los sitios…

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…

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…

The paper presents a case study illustrating a collaborative problem solving process in Virtual Communities of Practice. The process relies on the existence of an underlying shared knowledge base – a repository of resources, and is carried out collaboratively by…

Defeasible argumentation is one of the approaches that attempt to address the challenges arising when we reason defeasibly, with several formalisms in the literature reaching a mature state. Nowadays, several of them started shifting their semantics towards a dialectical characterization.…
