Triage is medical term referring to the process of prioritizing patients based on the severity of their condition so as to maximize benefit (help as many as possible) when resources are limited. Bug Report triaging is a process where tracker issues are screened and prioritized. Triage should help ensure that all reported issues are properly managed - bugs as well as improvements and feature requests. The large number of new bug reports received in bug repositories of software systems makes their management a challenging task. Handling these reports manually is time consuming, and often results in delaying the resolution of important bugs. The most critical issue related with bug reports is that their number is vast and most of these are duplicates of some previously sent bug report. The solution to this problem requires that bug reports are to be categorized in groups where each group consist of all the bug reports which belongs to the same bug, and the number of groups is equal to the number of unique bugs addressed so far. Bug report corresponding to some new bug is to be placed in a separate group followed by its duplicates, if any. Classifying weather a bug report that arrived through a user, written in a natural language, is a duplicate or unique report is a time consuming task, especially when the number of bug reports that are received is large. Thus, this process needs to be automated. Bug reports have textual, contextual and categorical features and these features needs to be extracted for checking of duplicates and non duplicates. Moreover, in the group of reports, a particular report can be specified as master and all the reports that corresponds to the same bug are to be linked to it. Thus, duplicates need not be discarded so as to provide later, a complete description of the bug. In this paper, a much more extended set of textual features is considered for bug report duplicacy checking. Support Vector Machine classifier is used for classification of the incoming bug report as duplicate of non-duplicates. The simulation of the prescribed model is done using R Statistical Package. A sample of bug reports from Mozilla repository is considered, Results of the simulation model establishes the fact that Proposed classifier has higher efficiency as compared to existing technique BM25F which employs 25 feature sets.
