Alternative Ranking Distance Metrics for Fault-Focused Clustering in Parallel Fault Localization

Generating fault-focused clusters is a common practice used in parallel fault localization where fault-focused rankings that are likely leading to the same firstly identified faulty statement are grouped together.With respect to the performance of fault-focused clustering and fault localization cost, one critical impact factor is the metric used to measure the distance between two rankings.Current work prefers using Kendall tau distance for its fitness in computing the ranking disagreement.In this paper, we tend to apply two other well-established ranking distance metrics, Spearman's Footrule and a set intersection-based measure, to fault-focused clustering and cross compare the parallel fault location performance of using these three distinct distance metrics.
