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…

Focusing on the Ontology Change problem, we consider an environment where Description Logics (DLs) are the logical formalization to express knowledge bases, and the integration of distributed ontologies is developed under new extensions and modifications of the Belief Revision theories…

The theory change area have defined several operators trying to model the dynamic of knowledge. The goal of this work is to introduce a preprocessor of perceptions that could be part of an agent. The purpose of the preprocessor is…

When using tableaux algorithms to reason about Description Logics (DLs), new information is inferred from the models considered while trying to achieve knowledge satisfiability. By focusing the ontology change problem, we consider an environment where DLs are the logical formalization…

A grande maioria dos Sistemas de Gerenciamento de Aprendizagem predominantemente em uso no ensino com suporte computacional são estáticos e lineares, ou seja, apresentam o mesmo conteúdo instrucional para os diversos estudantes sem considerar o nível de aquisição de conhecimentos…

En un contexto educativo, hay esencialmente dos modos de aprovechar la capacidad de proceso y almacenamiento de una computadora: a) producir sistemas basados en el conocimiento (tales como servicios de Internet WWW, enciclopedias multimedia, etc.) en los que el usuario…

El presente artículo trata la aplicación de un sistema experto capaz de determinar la factibilidad de funcionamiento de una máquina térmica desde el punto de vista termodinámico, mediante el análisis del diseño de un ciclo de potencia, el ciclo Joule…

En este trabajo se propone una metodología para mejorar las predicciones de incendios forestales. Utilizando un simulador ya desarrollado, se utiliza un algoritmo genético para realizar una búsqueda efectiva de parámetros de entrada tal que estos parámetros logren una buena…

As a contribution to consider software projects to be risk investments, it is important the full standardization of either the planning methodology (as a subset of project management methodology) and the effort estimation method. We think there is important and…
