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…

Spatial data warehouses (SDW) rely on extended multidimensional (MD) models in order to provide decision makers with appropriate structures to intuitively analyse spatial data. Several SDW development approaches provide a conceptual modeling and some guidelines in order to obtain logical…

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…

Uno de los problemas actuales en el dominio de la salud es reutilizar y compartir la información clínica entre profesionales, ya que ésta se encuentra escrita usando terminologías específicas. Una posible solución es usar un recurso de conocimiento común sobre…

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…

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…

Cuestionario empleado en el estudio sobre uso, conocimiento y percepción de Internet en la vida cotidiana de los estudiantes; este cuestionario ha sido empleado con alumnos con diferentes perfiles (edad y estudios) y de diferentes países., Questionnaire used in the…

El proyecto KNOW pretende añadir significado, conocimiento y razonamiento a las tecnologías actuales de Procesamiento del Lenguaje Natural., The KNOW project aims to add meaning, knowledge and reasoning to current Natural Language Processing technologies., TIN2006-15049-C03.

In this paper, a restricted domain question answering (QA) system is described. The design architecture of this QA system and the features that allow the adaptation of the QA system to the medical domain are also presented. The advantages of…
