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…

In this paper, we present SEDiL, a Software for Edit Distance Learning. SEDiL is an innovative prototype implementation grouping together most of the state of the art methods that aim to automatically learn the parameters of string and tree edit…

Este trabajo constituye un primer intento de abordar la detección automática de sujetos elididos y de construcciones impersonales en portugués de Brasil, una tarea que no nos consta que se haya llevado a cabo previamente en esta lengua. Para ello,…

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…

A data warehouse (DW) system stores data from multiple data sources in integrated form and provides capabilities for monitoring business operations to ensure compliance to strategic goals. As such, DWs constitute a fundamental building block for Business Intelligence (BI) operations.…

The 2nd International Workshop on Business intelligence and the WEB (BEWEB) was co-located with the EDBT/ICDT 2011 Joint Conference in Uppsala (Sweden) on March 25, 2011. BEWEB intends to be an international forum for researchers and practitioners to exchange ideas…

This thesis is focused on temporal information processing, which is a task framed in the field of natural language processing. The aim of this task is to obtain the temporal location and ordering of the events expressed in text or…

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…

Data mining is one of the most important analysis techniques to automatically extract knowledge from large amount of data. Nowadays, data mining is based on low-level specifications of the employed techniques typically bounded to a specific analysis platform. Therefore, data…

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…
