In the information age, knowledge leads to profits, power and success. As an ancestor of data mining, machine learning has concerned itself with discovery of new knowledge on its own. This paper presents experiment results produced by genetic algorithms in…

The development of systems with the ability to reason about change notion and actions has been of great importance for the artificial intelligence community. The definition and implementation of systems capable of managing defeasible, incomplete, unreliable, or uncertain information has…

En este trabajo analizaremos comparativamente las ediciones en español y portugués de la
enciclopedia El Tesoro de la Juventud. Así como en varios países del mundo, las traducciones
de la enciclopedia The Book of Knowledge tuvieron enorme suceso editorial en…

La Sociedad de la Información y el Conocimiento con su constante evolución tecnológica ha traído aparejados grandes y acelerados cambios sociales en los más variados aspectos de nuestra vida diaria. Y que ocurre con el Derecho? Por supuesto aprovecha las…

O projeto da rede corporativa de uma empresa requer que sejam bem conhecidas as características, necessidades e tendências de evolução do seu ambiente de informática, as tecnologias e tipos de equipamentos de rede disponíveis no mercado e como tais tecnologias…

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…

O artigo trata da questão da poluição atmosférica e do aquecimento global, fazendo um estudo do Protocolo de Kyoto e questões de natureza ética. Este artigo objetiva relacionar desenvolvimento sustentável, mecanismos de desenvolvimento limpo e mercado de créditos de carbono.…

Associating the pattern in text data with the pattern with time series data is a novel task. In this paper, an approach that utilizes the features of the time series data and domain knowledge is proposed and used to identify…

Adaptive systems behavior based on user models appear promising, mostly for complex environments such as mixed reality environments (MRE).
An MRE comprises a virtual representation of the reality as well as physical objects augmented with virtual features. These objects are…

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…
