Cualquier trabajo en ingeniería ontológica debe estar fundamentado en un protocolo de directrices bien definidas que no sólo organicen la estructuración de la ontología sino que además ayuden a determinar sus unidades ontológicas y propiedades. Una sólida metodología para el…

When training hidden-Markov-model-based part-of-speech (PoS) taggers involved in machine translation systems in an unsupervised manner the use of target-language information has proven to give better results than the standard Baum-Welch algorithm. The target-language-driven training algorithm proceeds by translating every possible…

En este trabajo se propone un modelo fractal —la herramienta matemática empleada por Mandelbrot en el estudio de fenómenos naturales de nuestro entorno— para dar cuenta de la propagación de la ciencia desde una nueva perspectiva, lo que nos permite…

La variante translingüe de la detección de plagio automática trata de detectar plagio entre documentos en diferentes idiomas. En los últimos años se han propuesto una serie de aproximaciones que hacen uso de tesauros, modelos de alineamiento o diccionarios estadísticos…

Current model-driven Web Engineering approaches (such as OO-H, UWE or WebML) provide a set of methods and supporting tools for a systematic design and development of Web applications. Each method addresses different concerns using separate models (content, navigation, presentation, business…

When building Hypermedia/Web Applications, (different) designers are often faced with the same problems over and over again. Those recurring problems soon yield elegant solutions, which can be conveniently described as design patterns. In this paper we present two patterns for…

La personalización de entornos ha suscitado un gran interés desde el punto de vista de los métodos de modelado conceptual de aplicaciones web. Ello es debido al efecto que tienen las políticas de personalización sobre todo el ciclo de desarrollo…

An audience driven philosophy for web site design takes the different target audiences as an explicit starting point, and organizes the basic navigation structure accordingly. However, for the designer it is not always easy, or sometimes even impossible, to assess…

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…

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…
