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…

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…

La variante translingüe de la detección de plagio automática trata de detectar plagio entre documentos en diferentes idiomas. En los últimos años se han propuesto una serie de aproximaciones que hacen uso de tesauros, modelos de alineamiento o diccionarios estadísticos…

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…

A lo largo de la última década se está produciendo un crecimiento vertiginoso tanto del desarrollo de nuevas tecnologías móviles inteligentes (dispositivos Smartphone y Tablet) como de su uso (a través de gran cantidad de aplicaciones). Por otro lado, en…

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…

La categorización de textos cortos es, hoy en día un área importante de investigación debido a que gran parte de la información que recibimos y con la cual trabajamos habitualmente tiene esta característica (e-mails, mensajes de texto, resúmenes de noticias,…

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.…

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…
