abstract: Our ability to process clinical data has been limited by our inability torepresent clinical data in a widely accepted standardized format. Should astandardized format be adopted that does not have a logical foundation, ourability to process this information will still be limited, becauseoperations such as determining equivalencies between terms and combinationsof other terms cannot be automated reliably. A logical foundation isnecessary for the development of sound and general models forrepresentation of clinical data; such models may include detailed models oftime, anatomy, and uncertainty. In this paper, we propose a model forstandardizing the format of clinical data and for standardizingterminological definitions using conceptual graphs as a notation for logic.We use time as an example to show how conceptual graphs can representmodels upon which representation schemes are founded. Finally, we show howan existing terminology system, SNOMED International, can be enhanced tofit within this model.
