"Pushing" a Term
Here is what "pushing" looks like. We start with a new test "Stat Glucose Test" and assign it to the Lab Test class. We also provide the semantic information by linking it to "Glucose". As we start to look down the tree, we see the class "Chemical Test" which measures chemicals. Since the system knows glucose is a chemical, it can push Stat Glucose Test down under Chemical Test. We can repeat the process as many times as necessary until the new term rests under the most specific class, in this case, Plasma Glucose Test.
