本研究では，ユーザや開発プロセスに直接的に重大な影響を及ぼす不具合 (High Impact Bug) の検出手法の構築を目指している．本研究は次の３つに大きく分かれる：①ソフトウェア開発データの分析や開発者にインタビュー調査を実施し，「High Impact Bugの特徴」を体系化②体系化を元にHigh Impact Bugの検出手法を構築・評価③High Impact Bugの検出手法を，タスクの割当て手法に取り込み，有用性を評価．本年度では，②「High Impact Bug検出手法の構築」において構築したモデルをバグトリアージ手法に取り込み，「より優先度の高い不具合を，より優秀な開発者にタスクを割当てる手法」を構築した．本年度に実施した詳細を以下に示す．【1.タスクの優先度を考慮した不具合修正タスクの割当て手法の構築】High Impact Bug検出手法を組み込むために，不具合修正タスクの優先度を考慮した割当て手法を構築し，割当手法単体で評価した．本手法では，それぞれのタスクにおいて各開発者が適任である確率を機械学習を用いて求めており，それを優先度で重み付けし，より優秀な開発者により優先度の高い不具合が割り当たるように設計している．評価実験の結果，既存手法を用いた場合と比較し，提案手法は高優先度の不具合を優秀な開発者に割当てられることを確認した．【2．High Impact Bug検出手法を組み込んだ割当手法の実用性評価】次に，昨年度に構築した「High Impact Bug検出手法」で出力するタスクの優先度を利用し，上述の割当て手法でタスクを割当てた．評価実験を通じて，High Impact Bugの検出手法を用いた場合でも，修正すべき高優先度の不具合を残すことなく，リリースまでにより多くの不具合を修正できることを確認した．

In this study, we did a lot of research on the use of major information and High Impact Bug. This study is divided into three parts: 1. In the first half of this study, we did a lot of work in this study. in this study, we did a lot of work in this study. in this study, we did a lot of work in this study. "High Impact Bug" systematized 2-systematized "High Impact Bug" to show manipulation ","3High Impact Bug" to "manipulate", "High Impact Bug" to select "manipulation", "usefulness". This year, 2 "High Impact Bug" to show that the technique is not compatible with each other. The following is shown in the following instructions for this year's exhibition. [1. In the first part of the examination, the system is not in accordance with the correction system. The High Impact Bug system is used in the system. The correction system is not in accordance with the correction system. In this method, the operator is responsible for the accuracy of the operation. It is necessary to pay the price in advance, and to show that the operator has the advantage that there is no combination of equipment. The results of the test results are compared with those of the existing practice. The method of proposal is very high, and the operator of the show is not responsible for confirming the performance of the system. [2.High Impact Bug reports that the organization of the system is responsible for the use of the system]. Yesterday, the annual "High Impact Bug strategy" made an effort to make full use of the system, and the above-mentioned system is used in the first place. High Impact Bug said to use the method to correct the error caused by the high degree of error, which is not valid.
