It is also based on the distance between term a and b:

sim = 1 - d(a, b)/2/max_depth

where max_depth is the maximal depth (maximal distance from root) in the DAG. Similarly, d(a, b) can be the shortest distance or the longest distance via LCA.

There is a parameter distance which takes value of "longest_distances_via_LCA" (the default) or "shortest_distances_via_NCA":

term_sim(dag, terms, method = "Sim_Resnik_edge_2005",
    control = list(distance = "shortest_distances_via_NCA"))
