The goal of this article is to present the first results of a study looking forward to propose a model of software development for a physically distributed environment (United States and Brazil). Thus, the objective is to combine empirical and…

The genetic algorithms have seen applied in knowledge discovery and specially for discovering association rules. In this paper, we explore the use of di erent rule quality measures in the tness function in a genetic algorithm for discovering association rules.…

Con el fin de contribuir al conocimiento de los hábitos alimenticios y la relación hombre-animal durante el período Inca en el noroeste argentino, se realizó un estudio arqueozoológico del material proveniente del sitio Potrero-Chaquiago, provincia de Catamarca. Aparte del rol…

Analiza las políticas sanitarias del gobierno de Domingo Alfredo Mercante (1946-1952) – mano derecha de Juan Domingo Perón – en la provincia de Buenos Aires, Argentina, atendiendo a lo que fue una de sus más instigantes líneas de intervención: la…

Effective document retrieval using domain knowledge and semantics is one of the major challenges in Information Retrieval. Over the last years, there has been a growing interest in ontologies as an artifact for human knowledge representation and a critical component…

A fuzzy controller is usually designed by formulating the knowledge of a human expert into a set of linguistic variables and fuzzy rules. As it is well known, the use of prior knowledge can dramatically improve the performance and quality…

En este trabajo se formula una propuesta de arquitectura de integración entre sistemas de descubrimiento de conocimiento (adquisición automática) y sistemas basados en conocimiento (sistemas expertos). Se formulan consideraciones sobre la viabilidad de implementación de dicha arquitectura en función de…

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 of…

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…

Humans have always been intrigued by their ability to reason. We have constantly attempted to emulate this process, trying almost everything, from physiological explanations, to sociological accounts. The approach with possibly the longest tradition conceives this process as a mere…
