I use LibSVM in AuthorClaim (http://authorclaim.org) and svm_light in NEP (http://nep.repec.org). I found both very helpful. I would switch to LibSVM in NEP since it LibSVM is still actively being developed. Just using a simple binary term weighing scheme and default SVM parameters should get you a long way.
