One of the most difficult problems that humanity currently faces is the sustainable development of our society, i.e. how to meet the needs of the present without compromising the ability of future generations to meet their own needs. Solving this…

Data mining is at the core of the knowledge discovery process. However, an initial preprocessing step is crucial for assuring reliable results within this process. Preprocessing of data is a time-consuming and non-trivial task since data quality issues should be…

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…

El éxito en la búsqueda de conocimiento a partir de grandes cantidades de datos radica en la calidad de los mismos. Hasta ahora los aspectos de calidad de los datos se han enfocado principalmente a la limpieza de los datos:…

Actualmente, existen diversas metodologías que brindan soporte al desarrollo de RIAs haciendo énfasis en la etapa de desarrollo e implementación. Sin embargo, no consideran una etapa de análisis de requisitos específica para RIAs que resulta necesaria para poder determinar en…

En el presente trabajo se recogen las reglas de formación y los criterios de aplicación que se deberían llevar a cabo en cada situación para permitir la identificación automatizada de uno de los procesos de formación de palabras que tiene…

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…

Rich Internet Applications offer Web surfers a richer user experience, mainly due to better responsiveness and enhanced user interface capabilities. In recent years, existing design methodologies targeting traditional Web 1.0 applications were extended to also support RIAs. These extensions do…

Web engineering methods provide a systematic approach to develop complex and high quality Web applications. Many of these methods provide, in some way, personalization support. However, none of the existing Web methodologies provide a tool which allow the modeling, automatic…

Recently, existing design methodologies targeting traditional Web applications have been extended for Rich Internet Application modeling support. These extended methodologies currently cover the traditionally well-established design concerns, i.e. data and navigation design, and provide additional focus on user interaction and…
