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…

El objetivo de KNOW2 es avanzar en el desarrollo de un entorno integrado que permita la implantación a bajo coste de portales verticales de acceso a la información para dominios concretos. El proyecto tiene una duración de tres años y…

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…

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…

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…

Web engineering software development is facing continuous changes in technology implementation. This involves analysts, developers and designers to provide extra effort in the design and maintenance of Web applications in order to adapt them to changes in requirements and implementation…

En este artículo, se presenta una propuesta con base en MDWE (Model Driven Web Engineering) para soportar trazabilidad (elemento-a-elemento) aplicando modelos weaving. El método de diseño Web A-OOH (Adaptive Object Oriented Hypermedia) es aplicado para representar el modelo de requisitos,…

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:…
