Generally speaking, the larger-scale open source development projects support both developers and users to report bugs in an open bug repository. Each report that appears in this repository must be triaged for fixing it. However, with huge amount of bugs are reported every day, the workload of developers is so high. In addition, most of bug reports were not assigned to correct developers for fixing so that these bugs need to be re-assigned to another developer. If the number of re-assignments to developers is large, the bug fixing time is increased. So "who are appropriate developers for fixing bug?" is an important question for bug triage. In this paper, we propose an automated developer recommendation approach for bug triage. The major contribution of our paper is to build the concept profile(CP) for extracting the bug concepts with topic terms from the documents produced by related bug reports, and we find the important developers with the high probability of fixing the given bug by using social network(SN). As a result, we get a ranked list of appropriate developers for bug fixing according to their expertise and fixing cost. The evaluation results show that our approach outperforms other developer recommendation methods.
