The EFO Project
The Experimental Factor Ontology (EFO) is an application focused
ontology modelling the experimental factors in ArrayExpress. The
ontology has been developed to increase the richness of the annotations
that are currently made in the ArrayExpress repository, to promote
consistent annotation, to facilitate automatic annotation and to
integrate external data. The methodology employed in the development
of EFO involves construction of mappings to multiple existing domain
specific ontologies, such as the Disease Ontology and Cell Type
Ontology. This is achieved using a combination of automated and
manual curation steps and the use of a phonetic matching algorithm.
The ontology is evaluated with use cases from the ArrayExpress
repository and Gene Expression
Atlas.
We have also involed in the SWORD
project to develop a Software Ontology for resource description.
We have performed a semi-automated transformation of the Coriell
cell line catalogue to create an OWL ontology of over 27,000
classes.
