An empirical approach to logical clustering of software failure regions
empiricalapproac00hila.pdf (8.890Mb)Abstract
Previous work (Ginn, 1991) showed that faults in a program tend to cluster when viewed by the variables that affect execution and propagation of the fault (structural clustering). However, that study was quite preliminary and local in its investigation. This thesis examines clustering from two other perspectives, taxonomical (type of faults) and functional (area of affected functionality). The hypothesis tested was that faults tend to cluster when viewed from these perspectives
