【 摘 要 】

We seek to leverage enhanced expressivity in OWL 1.1 via property chain axioms with right identities inorder to organize and constrain anatomic concepts for use in clinical descriptions. Anatomic knowledgerepresented in SNOMED CT uses SEP triplets; we anticipate that property chains will allow a moreparsimonious organization of anatomic concepts. However, these constructs may lead to unanticipatedinference, especially when scaling to large numbers of concepts [1]. We used a bottom-up approachbased on targeted use case questions to iteratively develop a “micro theory” that both identifies the sensible locations of fractures in long bones and also supports logic-based classification of fractures. Alternative representations of the statement “fractures occur in bone” were explored with the aim of creating rich clinical descriptors that support classification for inference and data mining. The process of creating this micro theory is discussed, where pragmatic decisions were made with an intention of both constraining data entry and enabling inferences within the scope of the use cases.[First Paragraph]
