Rediscovery Datasets: Connecting Duplicate Reports
This provides a resource for researchers and practitioners to analyze defect rediscovery, potentially speeding up bug fixing and improving triaging, but it is incremental as it focuses on data collection rather than new methods.
The paper tackles the problem of duplicate defect reports in open source software by presenting three datasets mined from Bugzilla, containing approximately 914,000 reports over 18 years to capture inter-relationships among duplicates.
The same defect can be rediscovered by multiple clients, causing unplanned outages and leading to reduced customer satisfaction. In the case of popular open source software, high volume of defects is reported on a regular basis. A large number of these reports are actually duplicates / rediscoveries of each other. Researchers have analyzed the factors related to the content of duplicate defect reports in the past. However, some of the other potentially important factors, such as the inter-relationships among duplicate defect reports, are not readily available in defect tracking systems such as Bugzilla. This information may speed up bug fixing, enable efficient triaging, improve customer profiles, etc. In this paper, we present three defect rediscovery datasets mined from Bugzilla. The datasets capture data for three groups of open source software projects: Apache, Eclipse, and KDE. The datasets contain information about approximately 914 thousands of defect reports over a period of 18 years (1999-2017) to capture the inter-relationships among duplicate defects. We believe that sharing these data with the community will help researchers and practitioners to better understand the nature of defect rediscovery and enhance the analysis of defect reports.
