Description: Advances in high throughput techniques for the generation of protein-protein interactions have produced a wealth of data. Inherent to these techniques is a large amount of false positive results necessitating careful analysis of the data. In order to pursue further analysis of the interaction data without propagating false positive data into subsequent studies it is vital that researchers are able to filter interaction data to retrieve only the high quality records. Taking a subset of curated yeast interactions from BIND, Dip, MINT and IntAct as a high confidence set of interactions we collated a set of features that characterize the interaction. A randomly generated protein interaction subset serves as our low confidence or negative set. We developed a probabilistic framework for assigning confidence to binary protein interactions by training an SVM to deduce the likelihood, or confidence score, of a binary interaction based on its set of features.
