The discipline of software engineering was created to address poor quality of software. The human and social aspects are important issues in the process of software development. Therefore, studying human and social aspect in software engineering, as well as mining the social networks for developers, may help software engineers to improve the quality of software products. The International Workshop on Human and Social Aspect of Software (HSASQ) aims to provide a forum to bring together researchers, practitioners and experts in both social networks and software engineering to present and discuss their relevant results or experience in either social networks for developers and software quality. And the special emphasis will be put on the intersection of two fields. The HSASQ workshop will be co-located with QRS 2015.
