Medical concepts in clinical reports can be found with a high degree of variability of ex- pression. Normalizing medical concepts to standardized vocabularies is a common way of accounting for this variability. One of the challenges in medical concept normalization is the difficulty in comparing two concepts which are orthographically different in repre- sentation but are identical in meaning. In this work we describe a method to compare medi- cal phrases by utilizing the information found in syntactic dependencies. We collected a large corpus of radiology reports from our university medical center. A shallow semantic parser was used to identify anatomical phras- es. We performed a series of transformations to convert the anatomical phrase into a norma- lized syntactic depende...
