The anatomical subcategories generally follow the guidelines in [Ref 1]. Specifically, Cocoa has the following divisions: GO cellular component, Cell, Tissue, Multi Tissue structure, Organ, Organism sub division, Developing anatomy, and Pathological formations. The tag names mirror the phrases above, with underscores replacing spaces, thus: 'Pathological_formation' for 'Pathological formation'. Anatomical subcategorization is a work in progress and uncategorized items are still tagged as 'Body part'. The 'GO cellular component' and the 'Cell' subcategories function somewhat reliably at present (see evaluation results against some corpora).
Physiological conditions are also subcategorized thusly:
Organisms are divide into 3 subcategories, namely
Extended annotations are available only through the Web API. Set the 'outputFormat' parameter to 'b1':
