Inferring domain–domain interactions (DDIs) from protein–protein interactions (PPIs). Given the domain decomposition of proteins and a set of PPIs, DDI inference methods target identification of DDIs that mediate these interactions. Different formulations of the problem optimize different criteria, leading to different solutions for DDI inference problem.
