Current reasoning systems attempt to model an agent's knowledge and interaction with its environment in a symbolic manner. This environment, its world is generally dynamic and changing due to natural evolution or the actions of other agents that are a…

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…

This paper summarizes the main results developed in the author's PhD Thesis.
The main goal of the Thesis is to provide a formalization of defeasible argumentation oriented towards its computational treatment. In order to do this, an LDS-based logical framework…

El descubrimiento de conocimiento (KD Knowledge Discovery) consiste en la búsqueda de patrones interesantes y de regularidades importantes en grandes bases de información [Holsheimer y Siebes, 1991; Piatetski-Shapiro et al., 1991]. Al hablar de descubrimiento de conocimiento basado en sistemas…

The paper presents a formal model for a knowledge repository shared by members of a Virtual Community of Practice (VCPs), describes how the repository can be used to underpin collaborative problem solving, and how to build computer support for such…

In a multi-agent system, a group of individ- uals interact in a social context in order to boost their capabilities and enhance global per- formance. Each individual's action repertoire may be reduced, but it's social capability allows it to interact…

The book is intended to be used in an introductory and intermediate level course on computer networks, both whitin Computer Science and Electric Engineering scopes. One of its characteristics is that the entire research software is presented in Java, but…

Fontes de informações sobre medicamentos são na maioria das vezes inacessíveis aos usuários e
quando disponíveis existe uma barreira relativa ao conhecimento técnico, na maioria das vezes exigido para
a compreensão destas. Os centros de informações sobre medicamentos aparecem como…

Las especies vegetales con propiedades curativas han sido utilizadas por el hombre desde hace
miles de años con el fin de aliviar dolencias de diferentes tipos. Es así que las plantas medicinales y sus
preparaciones farmacéuticas tienen cada vez mayor…

The goal of this work involves the developing of an argumentation-based formalism that an agent could use for constructing plans. In this formalism, agents will have certain knowledge about the world, and a set of actions that they will be…
