Methods

IC_annotation

Denote k as the number of items annotated to a term t, and N is the number of items annotated to the root (which is the total number of items annotated to the DAG), IC for term t is calculated as:

IC = -log(k/N)

In current implementations in other tools, there is an inconsistency of defining k and N. Please see n_annotations() for explanation.

NA is assigned to terms with no item annotated.
