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…

Lawyers often need to look for previous similar legal cases when analysing new ones.
The more previous cases, the more time is spent. Classical search engines execute termbased retrieval, which may miss relevant documents as well as fetch several irrelevant…

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…

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…

Se evaluó el nivel de conocimiento y desempeño de Buenas Practicas Clínicas de los investigadores participantes en ensayos clínicos en ejecución en 5 centros asistenciales, desde febrero a abril de
2006. El nivel de conocimiento se evaluó mediante una encuesta,…

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…

La antropología económica nace presuponiéndose como una interdisciplina, un intercambio de conceptos, información y conocimientos entre las ciencias económicas y las antropológicas. En este trabajo analizamos primeramente algunos de sus problemas fundantes y las proyecciones de tales tópicos en las…

The Semantic Web attempts to reach a state in the future where everything on the Web will no longer be only machine-readable, but also machine-understandable. An ontology is an explicit specification of a conceptualization. A conceptualization is an abstract, simplified…

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…

Much effort has been dedicated to provide a general model of agents working in complex environments. This research focuses on the high level cognition used in determining the behavior of the agent.
The language of the Situation Calculus represents a…
