title: Semantic distribution study of noun*noun compounds in the Japanese CT clinical reports.
abstract: The purpose of this study is to investigate the distribution of the semantic relationships between the two atomic medical terms of the noun-noun compounds extracted from the clinical documents in Japanese. Only 29.9% of the compounds had the UMLS semantic relation defined (mainly including "location_of" and "adjacent_to"). The results indicated that the semantic relations defined in the UMLS semantic network are not enough for describing the noun-noun medical compounds extracted from the Japanese clinical reports.
