ICi_resnik_1995 TODO Add resnik citation p(c) defined as number of top down fashion path leading to c from the reachable leaves from c + 1 max_pc = max p(c) for all concepts. IC(c) = -log( p(c) / max_pc) IC is normalize considering formula given by Faria and al in order to produce results [0,1]. Faria D, Pesquita C, Couto FM, Falcão A: Proteinon: A web tool for protein semantic similarity. 2007. IC_norm(c) = IC(c)/ log(nbAnnot) Here nbAnnot = |V|
