Who shapes Web standards? Uncovering the main topics of interest in the W3C

This paper identifies the primary topics of interest of organizations participating in the World Wide Web Consortium (W3C), the leading standards body for the Web. Using publicly available data from the W3C website, we analyze the participation of member organizations in W3C groups, treating the number of representatives allocated to each group as a proxy for their interests. By applying topic modeling and similarity analysis to these participation patterns, we uncover clusters of related groups and shared priorities among organizations. The results reveal five prominent areas of focus -- Web, Ads & Privacy; High Performance; Credentials & Web of Things; Accessibility; and Payments -- and show that large enterprises, particularly those based in the United States, dominate participation in core Web development and advertising-related topics, while Japanese organizations are more active in the Web of Things. These findings offer insights into how various stakeholders influence the standardization process and how the Web may evolve in the coming years.
