The EarthCube Tools Webinar series, organized by the Science Committee of the NSF-sponsored EarthCube program, provides practical demonstrations of how EarthCube projects can help you to collect, access, share, and visualize geoscience data. Each one-hour webinar showcases an EarthCube funded project followed by ample time for questions and conversation.
Our next webinar will be held: Friday, Jan. 20, at 2 pm EST (11 am PST)
Community Inventory of EarthCube Resources for Geoscience Interoperability
Discovering, interpreting and re-using data across geoscience domains is a core EarthCube challenge. Metadata is often inconsistent and incomplete; repositories follow different domain standards and semantics; many datasets aren’t registered in catalogs and exist on individual web sites – these are some of the key obstacles faced by researchers. CINERGI is an EarthCube Building Block project (http://earthcube.org/group/cinergi) to create technology components that enable cross-disciplinary data discovery. Metadata descriptions harvested from geoscience repositories and through community contributions are automatically enhanced, which includes generation of relevant keywords based on text analytics, derivation of spatial extents, and validation of organization names mentioned in the metadata. Automatic generation of keywords, in turn, is based on a cross-domain bridge ontology, which integrates several existing geoscience ontologies and controlled vocabularies, and on GeoSciGraph, a system for text parsing, vocabulary management and semantic annotation. Once processed, the metadata records are indexed and republished as ISO-19115/19139 documents with embedded semantic references to the ontologies integrated in CINERGI, along with provenance information for each record, and made available via a search portal and web service requests. The webinar will describe the main system components (the metadata augmentation pipeline; the underlying CINERGI ontology and semantic services; services and user interfaces for resource discovery and access; and accompanying provenance and validation services), present the current state of the system, and demonstrate its use in several cross-domain data discovery use cases.
