Outline of Final Research Achievements

I developed an internal structure model of body site expressions and algorithm to analyze an expression to get the internal structure. The expression is to be normalized based on the structure. I surveyed the body site expressions and anatomical terminology and the result shows that it proves inadequate to extract anatomical terms from the expression for normalization. Therefore, normalization requires the anatomical knowledge. I surveyed an anatomical ontology developed in Japan and body site expressions and revealed what normalization requires the ontology and the natural language processing technique.
