|Title:||Improving the detection accuracy of evolutionary coupling|
|Abstract:||If two or more program entities (e.g., files, classes, methods) co-change frequently during software evolution, these entities are said to have evolutionary coupling. The entities that frequently co-change (i.e., exhibit evolutionary coupling) are likely to have logical coupling (or dependencies) among them. Association rules and two related measurements, Support and Confidence, have been used to predict whether two or more co-changing entities are logically coupled. In this paper, we propose and investigate a new measurement, Significance, that has the potential to improve the detection accuracy of association rule mining techniques. Our preliminary investigation on four open-source subject systems implies that our proposed measurement is capable of extracting coupling relationships even from infrequently co-changed entity sets that might seem insignificant while considering only Support and Confidence. Our proposed measurement, Significance (in association with Support and Confidence), has the potential to predict logical coupling with higher precision and recall.|
