In the last decade, the Web 2.0 brought technological changes in the manner of interaction and communication between users and applications, and among applications as well. Rich Internet Applications (RIA) offer user interfaces with a higher level of interactivity, similar…

Tesis doctoral en Informática realizada por Montse Cuadros y dirigida por Dr. Lluís Padró y Dr. German Rigau. La defensa de la tesis fue en la facultad de Informática de la Universitat Politècnica de Catalunya el día 22 de noviembre…

Hemos analizado las alineaciones a nivel de oración de dos corpus paralelos de textos originales y sus simplificaciones creados con diferentes objetivos. Hemos clasificado las alineaciones que se observan y diseñado un algoritmo de clasificación capaz de predecir si las…

Entre el método clásico y simbólico de desambiguación de sentidos (WSD) que utiliza representaciones semánticas profundas de oraciones y textos, y el método estadístico que utiliza información relativa a la co-ocurrencia de palabras, existe una tendencia reciente a usar métodos…

This article analyzes the appropriateness of a text summarization system, COMPENDIUM, for generating abstracts of biomedical papers. Two approaches are suggested: an extractive (COMPENDIUM E), which only selects and extracts the most relevant sentences of the documents, and an abstractive-oriented…

Several surveys have indicated that many data warehouses fail to meet business objectives or are outright failures. One reason for this is that requirement engineering is typically overlooked in real projects. This paper addresses data warehouse design from a business…

This paper describes a new method for cross-lingual textual entailment (CLTE) detection based on machine translation (MT). We use sub-segment translations from different MT systems available online as a source of cross-lingual knowledge. In this work we describe and evaluate…

Previous work on an interactive system aimed at helping non-expert users to enlarge the monolingual dictionaries of rule-based machine translation (MT) systems worked by discarding those inflection paradigms that cannot generate a set of inflected word forms validated by the…

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…

This paper presents an algorithm for identifying noun phrase antecedents of third person personal
