Current metrics
• 3 ontologies
– Biological process
– Molecular function
– Cellular component
•
•
•
•
•
26,933 terms
5 relationship types
47,000+ relationships
40,000,000+ annotations
88,193 species.
Future plans
• Cross products
• Function-process links
Cross products: Identify ontologies within ontologies – make computable
Intersection tags / cross products
[Term]
id: GO:0010064 ! embryonic shoot morphogenesis
intersection_of: GO:0010016 ! shoot morphogenesis
intersection_of: part_of GO:0009790 ! embryonic development
[Term]
id: GO:0010101 ! post-embryonic root morphogenesis
intersection_of: GO:0010015 ! root morphogenesis
intersection_of: part_of GO:0009791 ! post-embryonic development
Cross products (xp) in progress
• XPs being set up amongst GO ontologies.
• Also with:
cell type ontology,
uberon (anatomy) ontology,
ChEBI (chemical) ontology.
• 170+ new relationship types planned.
Link out to other ontologies:
• Open Biomedical Ontologies
– 54 compatible ontologies
– 26 other nearly compatible ontologies
