Association Patterns of Ontological Features Signify Electronic Health Records in Liver Cancer

Figure 2

Edge counting based on level 4 concepts: “liver finding,” “abdominal organ finding,” and “fatty liver.” (a) “Cirrhosis” at level 7 is the descendant of “liver finding,” edge count is 3. (b) Edge count between “hepatic fibrosis” and “liver finding” is 2. (c) “Splenomegaly” is the descendant of “abdominal organ finding” but not “liver finding.” Thus, edge count of “splenomegaly” with “abdominal organ finding” is 2 and that with “liver finding” is infinity. “Fatty liver” is a feature concept, and thus, the edge count with itself is 0.
