Ontology Quality Control

We are still using the ontology QC procedures we reported in October. These include:

Progress is summarized on the Ontology_QC_Metrics page.

Completed work

Function-process links

Cellular component organization

  • We have reorganized terms representing Processes affecting cellular components, including defining "organization" and "biogenesis" in the context of CCs. Small refinements are made as term requests and other questions arise.


Other completed work

  • Terms added based on discussions at the 2009 Society for Developmental Biology meeting
  • S. pombe GO slim created
  • OBO-Edit 2.0 released; more details in software report

Work in progress

The ontology development group (including "core" members and ad hoc participants) has made a great deal of progress in several areas.

Internal cross-products

Function-process links

GO slims

A review of the generic GO slim is under way, and is guiding some refinement of high-level terms .

Biological topics

Much work is going on in several areas of biology:

Other work in progress

  • Evaluating new link suggestions and mismatches from ChEBI cross-products
  • Work on relationships among multi-organism process regulation terms
  • Taxon triggers for annotation quality control
    • New workflow
    • "Sensu" information moving from synonyms to definitions
    • Meeting notes
