    Would SNOMED CT Benefit From Realism-Based Ontology Evolution?Werner Ceusters, Kent Spackman & Barry Smith - 2007 - AMIA Annual Symposium Proceedings 2007:105-109.
    If SNOMED CT is to serve as a biomedical reference terminology, then steps must be taken to ensure comparability of information formulated using successive versions. New releases are therefore shipped with a history mechanism. We assessed the adequacy of this mechanism for its treatment of the distinction between changes occurring on the side of entities in reality and changes in our understanding thereof. We found that these two types are only partially distinguished and that a more detailed study is required (...)

    The Significance of SNODENT.Louis Goldberg, Werner Ceusters, John Eisner & Barry Smith - 2005 - Medical Informatics Europe 2005: 737-742.
    SNODENT is a dental diagnostic vocabulary incompletely integrated in SNOMED-CT. Nevertheless, SNODENT could become the de facto standard for dental diagnostic coding. SNODENT's manageable size, the fact that it is administratively self-contained, and relates to a well-understood domain provides valuable opportunities to formulate and test, in controlled experiments, a series of hypothesis concerning diagnostic systems. Of particular interest are questions related to establishing appropriate quality assurance methods for its optimal level of detail in content, its ontological structure, its construction and (...)

    Investigating Subsumption in DL-Based Terminologies: A Case Study in SNOMED CT.Olivier Bodenreider, Barry Smith, Anand Kumar & Anita Burgun - 2004 - In Proceedings of the First International Workshop on Formal Biomedical Knowledge Representation (KR-MED 2004). pp. 12-20.
    Formalisms such as description logics (DL) are sometimes expected to help terminologies ensure compliance with sound ontological principles. The objective of this paper is to study the degree to which one DL-based biomedical terminology (SNOMED CT) complies with such principles. We defined seven ontological principles (for example: each class must have at least one parent, each class must differ from its parent) and examined the properties of SNOMED CT classes with respect to these principles. Our major results are: 31% of (...)
