title: Semantic quality through semantic definition: refining the Read Codes through internal consistency.
abstract: Checks of internal consistency in controlled medical vocabularies facilitate their development and assist refinement of the underlying terminological model. Two simple checks of consistency between knowledge in the subtype hierarchy and that in semantic definitions of concepts are described. It is proposed that these checks are a helpful adjunct to, but not a replacement for, large-scale involvement of domain experts in construction of controlled vocabularies.
