Detecting Discussions of Technical Debt
share
Technical debt (TD) refers to suboptimal choices during software development that achieve short-term goals at the expense of long-term quality. Although developers often informally discuss TD, the concept has not yet crystalized into a consistently applied label when describing issues in most repositories. We apply machine learning to understand developer insights into TD when discussing tickets in an issue tracker. We generate expert labels that indicate whether discussion of TD occurs in the free text associated with each ticket in a sample of more than 1,900 tickets in the Chromium issue tracker. We then use these labels to train a classifier that estimates labels for the remaining 475,000 tickets. We conclude that discussion of TD appears in about 16 tracked Chromium issues. If we can effectively classify TD-related issues, we can focus on what practices could be most useful for their timely resolution.
