- A schematic view of the method. Step 1: Manual extraction of the image finding terms and their corresponding synonyms from the reports. Step 2: The concepts of the image finding terms defined in SNOMED CT were identified by using UMLS Terminology Services. Step 3: Edge counting of the semantic distances between the extracted terms and the level-4 feature concepts. Step 4: The feature concepts are weighted by (Step 4a) generic term weighting approach and (Step 4b) specific term weighting approach. Step 5: The feature vectors are generated. Step 6: Similarity scores between feature vectors are calculated by modified direction cosine
