Hi, I have certain clarifications on classification of entities and UMLS CUI mapping using cTakes. I tested with a clinical document that contains different lab experiments. The entity types were classified properly but the UMLS CUI is not mapping properly. For eg: The lab test "Hemoglobin A1c" is correctly classified as procedure. But the UMLS code is mapped to C0202054. When I check it in UMLS Metathesaurus browser, it returned different concept "Glucohemoglobin measurement" mapped to the CUI code. I am using umls 2011 ab dictionary. Can anyone suggest me how to improve the accuracy for UMLS cui mapping ?
Regards, Prasanna
