	Research & Publications Recently, we have been working on understanding and measuring the collaborative development of open source software (OSS) projects using entropy and information theory. Our work on quantifying the evolution of social communities in OSS projects with indices developed from information entropy is published in FSE 2022: n Liang Wang, Ying Li, Jierui Zhang, and Xianping Tao. QuantifyingCommunity Evolution in Developer Social Networks. InProceedings of the30th ACM Joint European Software Engineering Conference and Symposiumon the Foundations of Software Engineering (ESEC/FSE ’22), November 14�18, 2022, Singapore, Singapore. CCF-A. We propose an approach to measure the diversity of an OSS project’s forks with the Rao’s quadratic entropy, which is published in ASE 2023: n Liang Wang, Zhiwen Zheng, Xiangchen Wu, Baihui Sang, Jierui Zhang, and Xianping Tao. 2023. Fork Entropy: Assessing the Diversity of Open Source Software Projects’ Forks. In 38th IEEE/ACM International Conference on Automated Software Engineering (ASE 2023). We also conduct research on understanding the emotions during computer programming: n Yuqian Zhuang, Liang Wang, Mingya Zhang, Shan Lin, Hao Hu, and Xianping Tao. OPTES: A Tool for Behavior-based Student Programming Progress Estimation. CompSac 2023. Large swarms of UAVs is another case of large-scale, machine-based collective intelligence, compared to the global-scale human collective intelligence emerges from the cooperation around OSS projects. We have conducted research on enabling technologies of collective intelligence for UAVs using reinforcement learning and AI technologies: n 王文, 汪亮, 吴俊锋, 陶先平, 胡昊. 基于策略多样性熵指标的无人机群智系统激发-汇聚程度度量方法研究. 中国科学: 技术科学, 2022.
