Abstract
En 中文
Context: Time -dependent software ecosystem is a complex system, where there are many projects and developers. Recommending projects to developers in a time -dependent software ecosystem can improve their quality and development speeds. However, the time -dependence of projects and developers results in an increased difficulty of project recommendation. Objective: To better recommend projects to developers in a time -dependent software ecosystem, we propose a method of multi -objective optimization and integrated indicator -driven two -stage project recommendation, which is fulfilled according to the change of developer communities and their projects. Method: According to the change of developer communities and their projects, a method of multi -objective optimization and integrated indicator -driven two -stage project recommendation is fulfilled. In the first stage, a constrained multi -objective optimization model for project recommendation to developer communities is established, and an improved NSGA-II algorithm is adopted to solve this model, with the purpose of obtaining the recommended projects to a developer community. For the second stage, an integrated indicator for project recommendation to developers is built to determine the developers of a project. Results: The proposed method is applied to project recommendation for nine time -dependent software ecosystems in GitHub, and compared with six state-of-the-art ones. The experimental results show that our method has significant advantages in recommendation accuracy and efficiency. Conclusion: According to the experimental results, we conclude that the proposed method can timely and accurately recommend projects to developers in a time -dependent software ecosystem, which reduces the difficulty of solving the problem of project recommendation.
