no code implementations21 Mar 2019 Marcos Martínez-Romero, Martin J. O'Connor, Attila L. Egyedi, Debra Willrett, Josef Hardi, John Graybeal, Mark A. Musen

The results show that our approach is able to use analyses of previous entered metadata coupled with ontology-based mappings to present users with accurate recommendations when authoring metadata.

Metadata in the BioSample Online Repository are Impaired by Numerous Anomalies

no code implementations3 Aug 2017 Rafael S. Gonçalves, Martin J. O'Connor, Marcos Martínez-Romero, John Graybeal, Mark A. Musen
