Abstract
A methodology for in situ migration of a hand-crafted DAG (Directed Acyclic
Graph) to an explicitly described, structurally validated OWL version is presented.
The original DAG is a dynamic entity, being updated daily. Well known untangling
methodologies recommend wholesale re-coding in one big hit. Unable to do this, we
tackle portions of the DAG, dissecting lexical phrases used as terms to property
based descriptions in OWL. Some portions of the Gene Ontology are amenable to
this, others need more human input. OWL offers benefits at all stages. The different
levels of expressivity are presented in a model called “feature escalator”, where the
user can choose the expressivity needed in each level. The results of applying the
methodology to some areas of the Gene Ontology demonstrate the validity of the
methodology to migrate DAGs to more expressive and formal languages like OWL.
