In this 40-min tutorial, attendees will learn how to mine fine-grained social networks from any git repository using git2net. Git repositories are used for a wide range of applications, such as the collaboration on scientific publications and joint collections of code snippets to fully-featured coding schools and popular software projects such as Linux or Firefox. The repositories link all changes made in a set of files to their corresponding authors. In addition, most git repositories, e.g., those of Open Source software projects, are freely accessible to researchers. Therefore, they represent rich and accessible sources of data on social interactions. With git2net, attendees will learn how to utilize git data for mining temporal interaction networks between authors of the repository.
