I am working on human protein protein interaction I need to run SVM I need a negative data set comprising of non interacting protein pairs how to generate  these.
 I found this database Negatome (http://mips.helmholtz-muenchen.de/proj/ppi/negatome/) but the the problem is it talking about most mammals I cant restrict my search to human.
Is there any other database containing human non interacting protein pairs or is there any other method to do this. 
Thanks in advance.
The Negatome database contain some human proteins which you can extract. In addition, there's this [paper][1] (and data [here][2]). Also if your protein interaction data is from AP-MS, you may want to make use of the [CRAPome database][3].
