Las bases de datos geoespaciales temáticas en distintas escalas geográficas y temporales, son necesarias en multitud de líneas de investigación. Una de ellas es la gestión y alerta temprana de riesgos de desastres por amenazas naturales (inundaciones, huracanes, terremotos, etc.). Las noticias sobre éste tema se publican habitualmente en periódicos digitales de todo el mundo y comportan un alto contenido geográfico. Este trabajo pretende extraer automáticamente las noticias emitidas por canales de re-difusión web (conocidos por las siglas RSS en inglés) para georreferenciarlas, almacenarlas y distribuirlas como datos geoespaciales. Mediante técnicas de procesamiento de lenguaje natural y consultas a bases de datos de topónimos realizaremos la extracción de la información. El caso de estudio se aplicará para México y todos los componentes utilizados serán de código abierto
The thematic geospatial databases in different geographic and temporal scales are needed in many areas of research. One is risk and disaster management. The stories on this subject are published regularly online by newspapers worldwide, entailing a high geographical content. This work aims to automatically extract the news releases from web feeds (RSS/Atom) to stored and distributed them as geospatial data. For that we use natural language precessing techniques. The use case applies to Mexico and all the components used are open source
