How to compute the drug side-effect similarity of a pairs of drug.

A reference is here: http://science.sciencemag.org/content/sci/321/5886/263.full.pdf?casa_token=vWUzFtUaTaUAAAAA:Dm2au92Lb3XQ9Ap0ueMM_BSGDb_FWxfaWN2Oyeh9UUQOAutMTu0cBLDqJ9J-m53vSJSrYXHrqGi5zJE

However, it doesn't provide more details. Anyone know some package or software can easily do compute the similarity of drug side-effect?

I read the paper and they do not explain how they computed. Is there anyone can help us get through this?
