Description
Summary:This Paper presents a novel metric called Weighted Coupling Support (WCS) for predicting fault proneness. Our Metric measures a new measurement unit called weighted coupling support for each class of the object to rank them based on their fault proneness, which is based on the well-known HITS algorithm that measures hub and authority weights in link analysis, One of the advantage of our proposed metric is that it can be computed in a simpler (and in many cases, programming language independent) way as compared to some of the structural metrics. We empirically studied WCS for predicting fault-proneness of classes in a Large OpenSource Systems and fault prediction sensitivity compared with CBO. As the result, we found that the proposed WCScan predict fault proneness nearly with 98.7% sensitivity, which is around 42% sensible when compared to CBO.
