Transcript Cross_Products_dphx - Gene Ontology Consortium

Cross-Product Status in GO
Cross Products
Cross products are logical definitions of
GO terms that use ‘simpler’ terms in
combination to define a more complex
term
Why Cross-Products?
• Cross-products can be expressed in OWL
– Allows for automated checking of ontology logic
– Allows for the use TermGenie to automatically
place terms in the ontology
• Cross-products are necessary to integrate the
ontology with annotation extension data.
• Cross-products with external ontologies allow
us to leverage external expertise (ChEBI).

by reassortment of genes resulting in gene combinations different from those
that were present in the parents." [GOC:go_curators, ISBN:0198506732]

Cross-Products Come in 2 Flavours
• Internal Cross Products
– Cross products that consist of terms that are in GO
(MF, BP, CC).
• External Cross Products
– Cross products that consist of a term from GO and
a term from another ontology

Next step: Cell Ontology
• The cell ontology is already being used in
annotation extensions
• It is critical that we also incorporate cell
information into GO logical definitions.
