Clone Detection on Large Scala Codebases
Wahidur Rahman, Yisen Xu, Fan Pu +7
Code clones are identical or similar code segments. The wide existence of code clones can increase the cost of maintenance and jeopardise the quality of software. The research comm…
Nopol: Automatic Repair of Conditional Statement Bugs in Java Programs
Jifeng Xuan, Matias Martinez, Favio Demarco +5
We propose NOPOL, an approach to automatic repair of buggy conditional statements (i.e., if-then-else statements). This approach takes a buggy program as well as a test suite as in…
Automatic Repair of Real Bugs in Java: A Large-Scale Experiment on the Defects4J Dataset
Matias Martinez, Thomas Durieux, Romain Sommerard +2
Defects4J is a large, peer-reviewed, structured dataset of real-world Java bugs. Each bug in Defects4J comes with a test suite and at least one failing test case that triggers the…
Towards Better Summarizing Bug Reports with Crowdsourcing Elicited Attributes
He Jiang, Xiaochen Li, Zhilei Ren +2
Recent years have witnessed the growing demands for resolving numerous bug reports in software maintenance. Aiming to reduce the time testers/developers take in perusing bug report…
Automated Localization for Unreproducible Builds
Zhilei Ren, He Jiang, Jifeng Xuan +1
Reproducibility is the ability of recreating identical binaries under pre-defined build environments. Due to the need of quality assurance and the benefit of better detecting attac…
A Hybrid ACO Algorithm for the Next Release Problem
He Jiang, Jingyuan Zhang, Jifeng Xuan +2
In this paper, we propose a Hybrid Ant Colony Optimization algorithm (HACO) for Next Release Problem (NRP). NRP, a NP-hard problem in requirement engineering, is to balance custome…
Approximating the Backbone in the Weighted Maximum Satisfiability Problem
He Jiang, Jifeng Xuan, Yan Hu
The weighted Maximum Satisfiability problem (weighted MAX-SAT) is a NP-hard problem with numerous applications arising in artificial intelligence. As an efficient tool for heuristi…
Approximate Backbone Based Multilevel Algorithm for Next Release Problem
He Jiang, Jifeng Xuan, Zhilei Ren
The next release problem (NRP) aims to effectively select software requirements in order to acquire maximum customer profits. As an NP-hard problem in software requirement engineer…
A Random Walk Based Algorithm for Structural Test Case Generation
Jifeng Xuan, He Jiang, Zhilei Ren +2
Structural testing is a significant and expensive process in software development. By converting test data generation into an optimization problem, search-based software testing is…
Automatic Bug Triage using Semi-Supervised Text Classification
Jifeng Xuan, He Jiang, Zhilei Ren +2
In this paper, we propose a semi-supervised text classification approach for bug triage to avoid the deficiency of labeled bug reports in existing supervised approaches. This new a…
Solving the Large Scale Next Release Problem with a Backbone Based Multilevel Algorithm
Jifeng Xuan, He Jiang, Zhilei Ren +1
The Next Release Problem (NRP) aims to optimize customer profits and requirements selection for the software releases. The research on the NRP is restricted by the growing scale of…
Debt-Prone Bugs: Technical Debt in Software Maintenance
Jifeng Xuan, Yan Hu, He Jiang
Fixing bugs is an important phase in software development and maintenance. In practice, the process of bug fixing may conflict with the release schedule. Such confliction leads to…
