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…

We identify different kinds of relevance relations between formulas that emerge in the process of belief revision. Informal definitions for alternative notions of relevance are suggested and a set of schemas and intuitive postulates for formalizing these notions are proposed.

Los paradigmas, las técnicas y las prácticas producto de tradiciones regulan las formas de transmisión del saber, estableciendo las concepciones de sujeto, así como las nociones de cuerpo, de prácticas corporales y, sobre todo, de cómo se educa lo “corporal”.

Una nueva filosofía de Management tiene el objetivo de capturar, diseminar y rehusar el conocimiento disperso que poseen las organizaciones y que junto a sus recursos humanos constituyen su Capital Intelectual, que forma parte de su activo más importante en…

The environmental crisis in our contemporary, globalized world, is facing a paradigm: the company now has a major technological development, and is also a society that destroys most in history. All the achievements of our civilization provide various negative factors,…

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…

In the last few years, several studies have emphasized the use of ontologies as an alternative to organization of the information.
The notion of ontology has become popular in fields such as intelligent information integration, information retrieval on the Internet,…

The aim of this work is to relate two apparently independent concepts as belief revision and relevance. We propose a formal characterization for the notion of (ir)relevance by means of a set of postulates. Then we define (ir)relevance using change…

This work describes the ontology construction process for the development of an Intelligent System for the Organization and Retrieval of Knowledge in Biodiversity – SISBIO. The system aims at the production of strategic information for the biofuel chain Two main…

Information Retrieval Systems normally deal with keywordbased technologies. Although those systems reach satisfactory results, they aren’t able to answer more complex queries done by users, especially those directly in natural language. To do that, there are the KnowledgeBased Systems, which…
