A Visual Bug Report Analysis and Search Tool

According to recent work, duplicate bug report entries in bug tracking systems impact negatively on software maintenance and evolution productivity due to, among other factors, the increased time spent on report analysis and validation, what in some cases take over 20 minutes. Therefore, a considerable amount of time is lost mainly with duplicate bug report analysis. In order to solve this problem, this work presents and evaluates a tool based on Information Visualization techniques, aiming to assist developers during analysis and identification of duplicate bug reports. The tool features development was supported by a survey conducted with several developers in order to identify the best opportunities for visualization techniques, according to the cognitive process for understanding bug reports informa-
