BACKGROUND: Computational comparative analysis of multiple genomes provides
valuable opportunities to biomedical research. In particular, orthology analysis
can play a central role in comparative genomics; it guides establishing
evolutionary relations among genes of organisms and allows functional inference
of gene products. However, the wide variations in current orthology databases
necessitate the research toward the shareability of the content that is generated
by different tools and stored in different structures. Exchanging the content
with other research communities requires making the meaning of the content
explicit. DESCRIPTION: The need for a common ontology has led to the creation of
the Orthology Ontology (ORTH) following the best practices in ontology
construction. Here, we describe our model and major entities of the ontology that
is implemented in the Web Ontology Language (OWL), followed by the assessment of
the quality of the ontology and the application of the ORTH to existing orthology
datasets. This shareable ontology enables the possibility to develop Linked
Orthology Datasets and a meta-predictor of orthology through standardization for
the representation of orthology databases. The ORTH is freely available in OWL
format to all users at http://purl.org/net/orth . CONCLUSIONS: The Orthology
Ontology can serve as a framework for the semantic standardization of orthology
content and it will contribute to a better exploitation of orthology resources in
biomedical research. The results demonstrate the feasibility of developing
shareable datasets using this ontology. Further applications will maximize the
usefulness of this ontology.
