mapping the stanford parser's dependency relation to the minipar's relations.

Hi, guys.
I want to extract information used the rule based strategy which is quite natural given the well defined relations. Now, I have the rule contained the dependency relations extracted from Minipar. The relations set is (mod, pnmod, subj, s, obj, obj2 and desc). Now I want to switch another parser Stanford Parser, and there are some differences in comparison with Minipar. So how to mapping the follwoing minipar's relation to stanford parser's.

mod, pnmod, subj, s, obj, obj2 and desc

Thands a lot.
