La subjetivización del de que en el español de Colombia

This paper deals with the phenomenon known as dequeísmo in Spanish, in particular with the semantic differences between canonical sentences with que and dequeísta sentences. I analyze previous corpus studies of dequeísmo, test their predictions with an independent corpus of spoken Colombian Spanish, and finally carry out a logistic regression to test new possible parameters that might influence...

Utilizando WordNet para Complementar la Información de Entrenamiento en la Identificación del Significado de las Palabras

La desambiguación del significado de las palabras se ha desarrollado como una subárea del Procesamiento del Lenguaje Natural (PLN), donde el objetivo es determinar el sentido correcto de aquellas palabras que tienen más de un significado, no es una tarea final en sí misma, sino una tarea intermedia necesaria en variadas aplicaciones del procesamiento del lenguaje natural. La resolución de la am...

Desarrollo de Sistemas Basados en Componentes Utilizando Diagramas de Secuencia

In the world we live, software solutions are more and more demanded. These solutions must be not only of excellent quality, but their development costs and time must be as minimal as possible. In this context, component reuse, is an essential research line. However, software development using components cannot be restricted to the selection of components syntactic and semantically compatible wi...

Comparativo empírico de medidas de diversidad en problemas de optimización evolutiva con restricciones

Premature convergence is one of the central problems in evolutionary algorithms, and its main reason consists in the lack of diversity. In order to monitor diversity, special measures must be employed, which describe the population’s spread over the search space or according to the fitness values. Some diversity measures have been proposed for unconstrained optimization and their capability to ...
