The Nature subject ontology is a medium sized (~2530 entities) poli-hierarchical taxonomy developed at Nature Publishing Group in order to classify scientific publications.

The taxonomy is made available as a SKOS file and is being used in these pages in order to test and evaluate various taxonomy visualization techniques. The menu at the top lets you access these experiments.

Important: these visualization have been developed in 2014 so the information displayed is partly outdated. For more recent versions of the taxonomy see the SciGraph project.
