ACM Web Science Conference 2021: conference report

The 13^th ACM Web Science Conference was hosted online by the University of Southampton from 21--25 June, 2021. The annual event is inherently interdisciplinary, integrating computer and information sciences with a multitude of disciplines including sociology, economics, political science, law, management, language and communication, geography and psychology. It is unique in the way it brings these disciplines together in creative and critical dialogue. It focuses on the full scope of socio-technical relationships that are engaged in the World Wide Web, based on the notion that understanding the Web involves not only an analysis of its architecture and applications, but also insight into the people, organisations, policies, and economics that are affected by and subsumed within it. Since it was first held in Athens in 2009, the conference has been hosted in six countries around the world.
