Methods

It is based on the depth of the LCA term c and the longest distance between term a and b:

sim = 2*depth(c)/(len_c(a, b) + 2*depth(c))

where len_c(a, b) is the longest distance between a and b via LCA c. The denominator in the equation can also be written as:

len_c(a, b) + 2*depth(c) = depth(c) + len(c, a) + depth(c) + len(c, b)
                         = depth_c(a) + depth_c(b)

where depth_c(a) is the longest distance from root to a passing through c.
