The integration and the mining of repositories are crucial tasks in that should be effectively and efficiently executed in many engineering and scientific domains.

As an example, novel techniques for precision medicine can be designed and implemented by leveraging on big data, semantic artifacts and artificial intelligence methodologies and techniques, as well as, the integration of biomedical data, including omics and multimedia bioimages, has become crucial for gaining a comprehensive understanding of specific diseases.

Moreover, software engineering practices can be improved by uncovering interesting and actionable information about software systems and projects using the vast amounts of software data stored in source control systems, defect tracking systems, code review repositories, archived communications between project personnel, question-and-answer sites, and CI build servers.
