A semantic-enabled meta-catalogue for intelligent geospatial information discovery

Geospatial catalogues which facilitate publishing, locating, managing and maintaining of distributed geo-resources, are widely used by the Earth science community for distributed data sharing and exchanging. However, because of the dissymmetry of data registered in the catalogues, users have to dig into several catalogues to find the needed information. In this paper, we proposed a framework of a seamlessly integrated meta-catalogue to address this problem. Meanwhile, semantic enabled reasoning and ranking were also introduced to enhance the traditional search capabilities.
