Just making sure... In order to get a similarity score for a phrase(term) pair, the UMLS database must have an entry that matches both phrases exactly. In other words, we won't get similarity scores for phrase pairs in which one or both phrases match a UMLS phrase partially?
Example queries using the web-interface. Query1: Term1: Paresis, Term2: Facial Paresis The similarity of Paresis (C0030552 http://atlas.ahc.umn.edu/cgi-bin/umls_similarity.cgi?word1=Paresis&word2=Facial+Paresis&sab=SNOMEDCT_US&rel=PAR%2FCHD&similarity=cdist&button=Compute+Similarity&sabdef=UMLS_ALL&reldef=CUI%2FPAR%2FCHD%2FRB%2FRN&relatedness=vector# ) and Facial Paresis (C0427055 http://atlas.ahc.umn.edu/cgi-bin/umls_similarity.cgi?word1=Paresis&word2=Facial+Paresis&sab=SNOMEDCT_US&rel=PAR%2FCHD&similarity=cdist&button=Compute+Similarity&sabdef=UMLS_ALL&reldef=CUI%2FPAR%2FCHD%2FRB%2FRN&relatedness=vector# ) using Conceptual Distance (cdist) is -1. Using: SAB :: include SNOMEDCT_US REL :: include PAR/CHD Query2: Term1: Paresis, Term2: Facial Warnings/Errors: Facial was not found in SNOMEDCT_US Thanks!
