Motivation and Goals

  • GO has become too large and complex to manage manually
  • Errors of omission and commission negatively impact users in many ways
  • Provide connections between GO and other ontologies

Methods

  • Create computable logical definitions (Cross Products) for GO terms using (a) other GO terms (b) terms from other ontologies
  • Use logic-based reasoning to find inconsistencies and errors

Results 2008

  • We have XP defs for 10712/27589 of GO terms
  • 1500-2000 links added or moved in GO based on reasoner results

The table below shows the number of XP defs that have been curated

Internal Cross Products

  • Cross-products that do not refer to terms outside GO

Regulation Cross Products

  • Performed two batch updates on GO, fixing 1000 and 500 links respectively
  • Moving towards automation of is_a link management

Cellular Component internal xps (new)

  • New spatial relations:
    • surrounded_by
    • adjacent_to

BP XP CC (new)

External Cross Products

  • Cross-products that refer to terms outside GO

Uber Anatomy Ontology (new)

CHEBI

  • XP:biological_process_xp_chebi
  • We are still missing links to many CHEBI terms
    • Basic text-matching methods don't work because CHEBI uses different terminological principles from GO
  • Pilot project using CHEBI to align GO with pathway dbs

Cell

  • ..

Goals for 2009

  • More curation of XP files
  • More automation, better integration with day to day ontology development
