Researchers mine the information in these software communities to understand developer behaviors, while previous works mainly focus on mining data within a single community. In this paper, we propose a novel approach to developer identity linkage and behavior mining across GitHub and StackOverflow. This approach links the accounts from two communities using a CART decision tree, leveraging the features from usernames, user behaviors and writing styles. Then, it explores cross-site developer behaviors through [Formula: see text]-graph analysis, LDA-based topics clustering and cross-site tagging. We conducted several experiments to evaluate this approach. The results show that the precision and [Formula: see text]-score of our identity linkage method are higher than previous methods in software communities. Especially, we discovered that (1) active issue committers are also active question askers; (2) for most developers, the topics of their contents in GitHub are similar to those of those questions and answers in StackOverflow; (3) developers\u2019 concerns in StackOverflow shift over the time of their current participating projects in GitHub; (4) developers\u2019 concerns in GitHub are more relevant to their answers than questions and comments in StackOverflow. <\/jats:p>","DOI":"10.1142\/s0218194017400034","type":"journal-article","created":{"date-parts":[[2018,1,29]],"date-time":"2018-01-29T03:17:32Z","timestamp":1517195852000},"page":"1409-1425","source":"Crossref","is-referenced-by-count":4,"title":["Developer Identity Linkage and Behavior Mining Across GitHub and StackOverflow"],"prefix":"10.1142","volume":"27","author":[{"given":"Yunxiang","family":"Xiong","sequence":"first","affiliation":[{"name":"School of Software, Shanghai Jiao Tong University, Shanghai 200240, P.
