Social coding facilitates the sharing of knowledge in Open-source community. In particular, issue reports, as an important knowledge in the software development, usually contain relevant information, and can thus be linked to other related issues manually. In a project, identifying and linking issues to potentially related issues would provide developers more targeted resource and information when they resolve target issues, thus improving the issue resolution efficiency. However, the current manual linking approach is in general time-consuming and mainly depends on the experience and knowledge of the individual developers. Therefore, investigating how to link related issues timely is a meaningful task which can improve development efficiency of open-source projects. In this study, the problem of linking related issues is formulated as a recommendation problem and a hybrid approach based on embedding models is proposed, combining the traditional information retrieval technique, i.e., TF-IDF, and the embedding models in deep learning techniques, i.e., word embedding and document embedding. The evaluation results show that, the proposed approach can improve the performance of traditional approaches, with a very strong application scalability.
