This paper presents a knowledge-based approach to facilitate the engineering design
process relating to spacecrafts. Because the design evolves over a long time and typically
involves individuals working at different locations and frequently for different
organizations, the degree of collaboration…

En este trabajo se ha desarrollado un sistema para la resolución computacional de la anáfora generada en el uso del lenguaje natural por pronombres (personales y demostrativos) y anáforas adjetivas en los diálogos. El método propuesto se basa en el…

En este artículo se presenta un sistema de aprendizaje supervisado para la desambiguación del sentido de las palabras. Dicho sistema se basa en los modelos de probabilidad condicional de máxima entropía. El conocimiento lingüístico se adquiere a partir de un…

Publicado en la Revista Colombiana de Tecnologías Avanzadas, Nowadays, satellite networks are a solution for rural and remote Internet connection where traditional terrestrial Internet urban access is not deployed, mainly, because of its cost. In this article we present results…

This thesis explores how doctors and nurses use documents to share their knowledge within and across healthcare settings. In addressing this question I draw on a 15-month, multi-sited ethnographic study in several pediatric health care settings, following patients from primary…

Most neural network learning algorithms cannot use knowledge other than what is provided in the training data. Initialized using random weights, they cannot use prior knowledge such as knowledge stored in previously trained networks. This manuscript thesis addresses this problem.…

MDFaces (Multi-Domain Faces) es un sistema inteligente capaz de reconocer conceptos relevantes en textos, procedentes de diferentes dominios, y mostrar información detallada y semántica relacionada con estos conceptos. Para su desarrollo se hace uso de una metodología que utiliza datos…

Despite earlier evidence to the contrary, recent inquiries appear to reach a consensus that the poor
pay more for food. However, these studies utilize samples drawn on the basis of prior
knowledge of unfair pricing strategies, proximity of volunteer surveyors,…

The limitations common to linear imaging techniques were formalized succinctly by Ernst Abbe in 1873. In his theory, each Fourier component of a signal propagates independently from the source to the detector, and the corresponding feature can be detected only…
