Improving Data Discovery for Metadata Repositories through Semantic Search

Chad Berkley, Shawn Bowers, Matthew B. Jones, Joshua S. Madin, Mark Schildhauer
2009 2009 International Conference on Complex, Intelligent and Software Intensive Systems  
We describe new semantic search features within the Metacat metadata system, which is used by many ecological research sites around the world for archiving their data using a standardized metadata format  ...  Our approach also extends Metacat to improve metadata search in multiple ways: (i) by expanding standard keyword searches with ontology term hierarchies; (ii) by allowing keyword searches to be applied  ...  While some improvements have been seen, both of these issues-depth of holdings and effective data discovery-are still problematic for most repositories.  ...

Spatial discovery and the research library

Sara Lafia, Jon Jablonski, Werner Kuhn, Savannah Cooley, F. Antonio Medrano
2016 Transactions on GIS  
It suggests a framework for an integrated data discovery mechanism and shows how publications may be linked to associated data sets exposed either directly or through metadata on Esri's Open Data platform  ...  The results demonstrate a simple form of linking data to publications through spatially referenced metadata and persistent identifiers.  ...  Some contemporary data management solutions address the need to enable the spatial discovery of resources, but do not enhance discovery of resources through semantic links.  ...
