Semantic Web for Earth and Environmental Terminology (SWEET)
Rob Raskin, Michael J. Pan · 2003
In this presentation, we describe our experiences with building and using large ontologies, with application to locating NASA Earth science data. We use OWL to represent the mutual relationships of scientific concepts and their ancillary space, time, and environmental descriptors. Background NASA’s Earth science mission is to improve our understanding of the integrated Earth system and its components, through the use of satellite data products. NASA makes its data and information products available at no charge to scientists and non-scientists. The motivation of our task is to improve the discovery of these products using tools that incorporate semantic understanding. In support of this effort, we developed a collection of ontologies for describing Earth science data and knowledge. An ontology-aided search tool was developed to demonstrate the use of these ontologies. Ontologies
