Abstract

Among clinical information, body site is fundamental because it may be a part of other important information such as patients’ conditions and procedures. Therefore the technique to catch the information is one of the most important components in clinical information processing. It requires normalization: to resolve notational variants and identify the concepts they indicate. But there is no promise that body site information used in clinical settings corresponds to exactly one anatomical concept. This paper studies correspondence relationship between body site expressions appeared in case reports and concepts defined in the Japanese anatomical ontology. The result shows that reduction occurred in 18.8% (29/154) of the body site expressions and 27.3% (42/154) correspond to two or more concepts. The detailed research of each cases demonstrates that the implementation of normalization technique require anatomical knowledge including regions and directions and a synonym dictionary in addition to internal structure analyzer of body site expressions.
