Anatomy Matching Algorithm

1.Lexical Match

•Normalize string, UMLS dictionary lookup, convert to concept-ID from thesaurus

2.Structure Match

•Similarity(reified nodes)
= Average(neighbors)

•Back-propagate to neighbors

3.Align Super-classes

•Super-class similarity = average similarity of children, grandchildren, great-grandchildren

•Adds 213 matches (to 3567)


	Step 3 is instead of the leaf-matching technique of Cupid, which is too expensive for a model this large.
