Methods

IC_height

For a term t in the DAG, denote d as the maximal distance from root (i.e. the depth) and h as the maximal distance to leaves (i.e. the height), the relative position p on the longest path from root to leaves via term t is calculated as:

p = (h + 1)/(h + d + 1)

In the formula where 1 is added gets rid of p = 0. Then the information content is:

IC = -log(p) 
   = -log((h+1)/(h+d+1))
