Este trabajo ha tenido como objetivo examinar el desempeño en lectura y escritura de niños que asisten a instituciones escolares primarias de la ciudad de La Plata. Su interés radica en la importancia que adquiere alcanzar niveles competentes de alfabetización…

The design of intelligent agents is greatly influenced by the many different models that exist to represent knowledge. It is essential that such agents have computationally adequate mechanisms to manage its knowledge, which more often than not is incomplete and/or…

Multiagent systems and online communities rely on rating systems to infer the reputation given to an individual within a particular context. The notion of reputation is essential for helping a given individual to trust in other individuals and for being…

¿Qué es un quiebre epistemológico? ¿Qué implicancias tiene éste en la metodología de la investigación y la Educación Corporal? Pasar de un sesgo “pedagógico y didáctico con que se pensaba a la Educación Física” (Crisorio y otros: proyecto 11/H465) a…

Objetivo: Examinar o fenômeno clínico de homicídio seguido de suicídio (HS) a partir de um caso no qual o desfecho de suicídio não ocorreu por motivos alheios á vontade e ás ações do sujeito. Descrição do caso: Trata-se do caso…

Co-training can learn from datasets having a small number of labelled examples and a large number of unlabelled ones. It is an iterative algorithm where examples labelled in previous iterations are used to improve the classification of examples from the…

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…

Knowledge acquisition for systems based on knowledge can be called knowledge engineering, according to Feigenbaum (1980) who used the term to describe the reduction of a wide context of knowledge for a set of facts and rules. The term Knowledge…

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…

In this article we will introduce certain considerations that must be taken into account while implementing the change operations of the belief change theory. The abstract models of bellief change make no considerations in respecto to the internal structures of…
