The accuracy of the SZZ algorithm is pivotal for just-in-time defect prediction because most prior studies have used the SZZ algorithm to detect defect-inducing commits to construct and evaluate their defect prediction models. The SZZ algorithm has two phases to detect defect-inducing commits: (1) linking issue reports in an issue-tracking system to possible defect-fixing commits in a version control system by using an issue-link algorithm (ILA);and (2) tracing the modifications of defect-fixing commits back to possible defect-inducing commits. Researchers and practitioners can address the second phase by using existing solutions such as a tool called cregit. In contrast, although various ILAs have been proposed for the first phase, no large-scale studies exist in which such ILAs are evaluated under the same experimental conditions. Hence, we still have no conclusions regarding the best-performing ILA for the first phase. In this paper, we compare 10 ILAs collected from our systematic literature study with regards to the accuracy of detecting defect-fixing commits. In addition, we compare the defect prediction performance of ILAs and their combinations that can detect defect-fixing commits accurately. We conducted experiments on five open-source software projects. We found that all ILAs and their combinations prevented the defect prediction model from being affected by missing defect-fixing commits. In particular, the combination of a natural language text similarity approach, Phantom heuristics, a random forest approach, and a support vector machine approach is the best way to statistically significantly reduced the absolute differences from the ground-truth defect prediction performance. We summarized the guidelines to use ILAs as our recommendations.
