An Intelligent Duplicate Bug Report Detection Method Based on Technical Term Extraction

As the bug description data generated during the software maintenance cycle, bug reports are usually hastily written by different users, resulting in many redundant and duplicate bug reports (DBRs). Once the DBRs are repeatedly assigned to developers, it will inevitably lead to a serious waste of human resources, especially for large-scale open-source projects. Recently, many experts and scholars have devoted themselves to researching the detection of DBRs and put forward a series of detection methods for DBRs. However, there is still much room for improvement in the performance of DBR prediction. Therefore, this paper proposes a new method for detecting DBR based on technical term extraction, CTEDB (Combination of Term Extraction and DeBERTaV3) for short. This method first extracts technical terms from the text information of bug reports based on Word2Vec and TextRank algorithms. Then it calculates the semantic similarity of technical terms between different bug reports by combining Word2Vec and SBERT models. Finally, it completes the DBR detection task by combining the DeBERTaV3 model. The experimental results show that CTEDB has achieved good results in detecting DBR, and has obviously improved the accuracy, F1-score, recall and precision compared with the baseline approaches.
