A Bug Report Analysis and Search Tool and Its Validation

. According to recent work, duplicate bug report entries in bug trackers impact negatively on software maintenance and evolution productivity due to, among other factors, the increased time spent on report analysis. Such type of duplication is characterized by the submission of two or more bug reports that describe the same software issue. In this sense, this dissertation investigates and characterizes the problem of bug report duplication and proposes a solution to it.
