Using Source Code Density to Improve the Accuracy of Automatic Commit Classification into Maintenance Activities [article]

Sebastian Hönel, Morgan Ericsson, Welf Löwe, Anna Wingkvist
2020 arXiv   pre-print
We introduce source code density, a measure of the net size of a commit, and show how it improves the accuracy of automatic commit classification compared to previous size-based classifications.  ...  We also investigate how preceding generations of commits affect the class of a commit, and whether taking the code density of previous commits into account can improve the accuracy further.  ...  Acknowledgments We would like to thank the anonymous reviewers for their invaluable comments, which helped us to further improve this work.  ...

Toward the Automatic Classification of Self-Affirmed Refactoring [article]

Eman Abdullah AlOmar, Mohamed Wiem Mkaouer, Ali Ouni
2020 arXiv   pre-print
We challenge our model using a total of 2,867 commit messages extracted from well-engineered open-source Java projects.  ...  Specifically, we combine the N-Gram TF-IDF feature selection with binary and multiclass classifiers to build a new model to automate the classification of refactorings based on their quality improvement  ...  Using code-density based classification, they achieved up to 89% accuracy for cross project commit classification using LogitBoost classifier.  ...

On the Documentation of Refactoring Types [article]

Eman Abdullah AlOmar and Jiaqian Liu and Kenneth Addo and Mohamed Wiem Mkaouer and Christian Newman and Ali Ouni and Zhe Yu
2021 arXiv   pre-print
Yet, there is no systematic study that analyzes the extent to which the documentation of refactoring accurately describes the refactoring operations performed at the source code level.  ...  Commit messages are the atomic level of software documentation. They provide a natural language description of the code change and its purpose.  ...  Acknowledgments This material is based on work supported by the National Science Foundation under Grant No. 1757680.  ...

Leveraging Structural Properties of Source Code Graphs for Just-In-Time Bug Prediction [article]

Md Nadim, Debajyoti Mondal, Chanchal K. Roy
2022 arXiv   pre-print
We presented a method to convert the source codes of commit patches to equivalent graph representations and named it Source Code Graph (SCG).  ...  To understand and compare multiple source code graphs, we extracted several structural properties of these graphs, such as the density, number of cycles, nodes, edges, etc.  ...  Acknowledgements This work is supported by the Natural Sciences and Engineering Research Council of Canada (NSERC) and by two Canada First Research Excellence Fund (CFREF) grants coordinated by Global  ...

Behind the Scenes: On the Relationship Between Developer Experience and Refactoring [article]

Eman Abdullah AlOmar, Anthony Peruma, Mohamed Wiem Mkaouer, Christian D. Newman, Ali Ouni
2021 arXiv   pre-print
Previous refactoring surveys have shown that code refactoring activities are mainly executed by developers who have sufficient knowledge of the system's design and disposing of leadership roles in their  ...  However, these surveys were mainly limited to specific projects and companies. In this paper, we explore the generalizability of the previous results by analyzing 800 open-source projects.  ...  AlOmar et al ACKNOWLEDGMENTS We would like to thank the authors of Refactoring Miner for publicly providing it.  ...
