Methods

Sim_SimIC_2010

The IC method is fixed to IC_annotation.

The SimIC method is an improved correction method of the Relevance method because the latter works bad when p(c) is very small. The SimIC correction factor for MICA term c is:

1 - 1/(1 + IC(c))

Then the similarity is:

sim = (1 - 1/(1 + IC(c))) * IC_Lin 
    = (1 - 1/(1 + IC(c))) * 2*IC(c)/(IC(a) + IC(b))
