Geographic knowledge discovery (GKD) is the process of extracting information and knowledge from massive georeferenced databases. Usually the process is accomplished by two different systems, the Geographic Information Systems (GIS) and the data mining engines. However, the development of those…

Investigamos la posibilidad de obtener patrones semánticos a gran escala para cualquier lengua usando solamente análisis superficial y generalizaciones semánticas básicas. Siendo este un experimento exploratorio sólo hemos realizado una evaluación cualitativa. Hemos comparado varios patrones semánticos de traducción de…

This paper evaluates the different tasks carried out in the translation of pronominal anaphora in a machine translation (MT) system. The MT interlingua approach named AGIR (Anaphora Generation with an Interlingua Representation) improves upon other proposals presented to date because…

Obtaining an implementation of a data warehouse is a complex task that forces designers to acquire wide knowledge of the domain, thus requiring a high level of expertise and becoming it a prone-to-fail task. Based on our experience, we have…

Sometimes, the presence of objects difficult the observation of other neighboring objects. This is because
part of the surface of an object occludes partially the surface of another, increasing the complexitiy in the
recognition process. Therefore, the information which is…

Encontrar un formalismo adecuado para representar la paráfrasis constituye un reto para el Procesamiento del Lenguaje Natural. En este artículo, se analiza la distancia de edición de árboles como caso base para dicha representación. Los experimentos realizados utilizando Edit Distance…

MaltOptimizer es una herramienta capaz de proporcionar una optimización para modelos generados mediante MaltParser. Los analizadores de dependencias actuales requieren una completa configuración para obtener resultados a la altura del estado del arte, y para ello es necesario un conocimiento…

This work presents the main theories and models formulated with the purpose of offering a global overview on the acquisition of knowledge and skills involved in the initial development of expert competence. Setting from this background, we developed an empirical…

We develop a theory to explain the transition from stagnation to modern growth. We focus on the forces that shaped the evolution of total factor productivity in agriculture and manufacturing across history. More specifically, we build a multisector model of…

The extension to new languages is a well known bottleneck for rule-based systems. Considerable human effort, which typically consists in re-writing from scratch huge amounts of rules, is in fact required to transfer the knowledge available to the system from…
