Bug report assignment is an integral part of bug triaging process. It aims at assigning a suitable developer for the reported bug. The assigned developer edits the source code in order to resolve the bug. Existing bug assignment techniques use differ

The objective of this research work is to develop a proficient recommender system for effective bug triaging. To build this we initiated with introducing a novel time based model, Visheshagya, for bug report assignment. Subsequently, we propose a novel AHP based bug assignment approach, W8Prioritizer, based on bug parameter prioritization. We further extend our work for triaging Non-reproducible (NR) bugs, the bugs for which the developer faces difficulty in reproducing. However, certain fraction of these bugs gets fixed later. We propose a novel prediction model, NRFixer to predict the fixability of bug reports marked as NR. In the future, we plan to work on bug report assignment for fixable NR bugs using Visheshagya and W8Prioritizer. Overall our initial results are encouraging and shows the possibility of making a robust recommender system for effective bug report assignment for both reproducible (R) and NR bugs.

Software bugs are inevitable and fixing these bugs is a difficult and time consuming task. Bug report assignment is the activity of designating a developer who makes source code changes in order to fix the bug. Many bug assignment techniques have been proposed in the existing studies. These studies use different datasets, varied input and evaluation parameters to validate their work. This diversification in bug triaging results in perplexity among researchers. Hence, this paper organizes the work performed in bug triaging in a structured manner. This paper aims to present current state of the art to provide a structured consolidation of bug triaging approaches. The paper has identified six research questions under five dimensions to address the various aspects of bug triaging. 60 articles from 36 venues have been reviewed and categorized in order to organize and substructure existing work in the field of bug report assignment. This study will help researchers to wisely decide the weapons for bug triaging. Also, it will act as a ready reference for the bug triaging practitioners.
