IC_Zhou_2008

It is a correction of IC_Seco_2004 which considers the depth of a term in the DAG. The information content is calculated as:

IC = 0.5*IC_Seco + 0.5*log(depth)/log(max_depth)

where depth is the depth of term t in the DAG, defined as the maximal distance from root. max_depth is the largest depth in the DAG. So IC is composed with two parts: the numbers of offspring terms and positions in the DAG.
