Social interactions play a vital role in shaping technology evolution, especially in technology standards development involving multiple actors across the industry. However, previous studies mostly focus on the interactions between technology designs and socio-cognitive factors and pay little attention to the intertwined nature of social and material aspects of technologies. From the sociomaterial perspective, a key is to focus on the process of discursive materialization and its performative consequences in practice. Drawing on Orlikowski and Scott’s (2015) material-discursive perspective, this paper examines how the HTML5 (technology standard) evolves over time by investigating the processes of discursive materialization at the World Wide Web Consortium with the topic modeling techniques. The analysis shows that four fundamental mechanisms (process management, dialogical coordination, boundary work, and knowledge conversion) shape the evolution of HTML5. This study contributes to understanding processes of technology evolution from the sociomaterial perspective with a novel empirical approach.
