The National Drug File - Reference Terminology (NDF-RT) is a large and complex drug terminology. NDF-RT provides important information about clinical drugs, e.g., their chemical ingredients, mechanisms of action, dosage form and physiological effects. Within NDF-RT such information is represented using tens of thousands of roles. It is difficult to comprehend large, complex terminologies like N...

The Pharmacogenomics Knowledge Base (PharmGKB) [1] is a publicly available central resource for pharmacogenomics data and knowledge, which is being widely employed into clinical practice and thus requires using clinical terminologies. Hence, harmonizing PharmGKB drug data with well annotated drug terminologies will facilitate its integration with other related resources and support data represe...

Objectives: To evaluate the consistency of inferred drugclass membership relations in NDF-RT (National Drug File Reference Terminology). Methods: We use an OWL reasoner to infer the drug-class membership relations from the class definitions and the descriptions of drugs and compare them to asserted relations. Results: The inferred and asserted relations only match in about 50% of the cases. Con...

Clinical and epidemiological researchers across all medical specialties need tools and knowledge representations to support the classification, aggregation, and analysis of medication data. The National Drug File Reference Terminology (NDF-RT), a named standard for classifying medications, is developed by the US Department of Veterans Affairs (VA) as an extension to their National Drug File, wh...

Biomedical terminology and vocabulary standards play an important role in enabling consistent, comparable, and meaningful sharing of data within and across institutional boundaries, as well as ensuring semantic interoperability. The Veterans Affairs (VA) National Drug File Reference Terminology (NDF-RT) is a federally recommended standardized terminology resource encompassing medications, ingre...
