Explotación de información en el dominio geo-hídrico ecuatoriano utilizando tecnología semántica
Abstract
RESUMEN
En este artículo se presenta una propuesta para la explotación de información en el dominio geo-hídrico ecuatoriano, en sintonía con la tendencia actual respecto a la integración de datos de diferentes fuentes y la publicación de estos datos aplicando los principios de Linked Data. Esta propuesta utiliza como lenguaje de consulta GeoSPARQL, proporcionando la capacidad de operaciones espaciales para explotación y descubrimiento de recursos que representan entidades geográficas. Estos recursos están almacenados sobre repositorios de tripletas RDF distribuidos, que se corresponden con los datos de diferentes instituciones vinculadas al dominio geo-hídrico. Esta propuesta facilita la integración y explotación de información a partir de los enlaces existentes entre recursos que hacen referencia al mismo fenómeno del mundo real. Finalmente, los recursos explotados son visualizados en un visor gráfico MAP4RDF permitiendo una visión unificada de la realidad hídrica nacional. Este visor ha sido mejorado, constituyéndose también en un aporte tecnológico.

ABSTRACT
In this article, we present an approach for exploiting the information in the Ecuadorian geo-hydrological domain, in tune with current trends relative to data integration from different sources and the publication of these data by applying the principles of Linked Data. Our approach uses GeoSPARQL as query language, which provides the ability to perform spatial operations for exploiting and discovery of resources that represent geographic entities. These resources are stored on distributed RDF data stores, which correspond to data from different institutions involved in geo-hydrological domain. This proposal facilitates the integration and use of information from the existing links between resources that refer to the same real-world phenomenon. Finally, the resources exploited are displayed on a graphic tool named, map4rdf, allowing a unified vision of national hydric reality. This tool has been enhanced in our approach, becoming also in a technological contribution.
Keywords: GeoSPARQL, Geo Linked Data, data discovery, federal queries.
