Aboucaya, William2021-05-122021-05-122021https://dl.eusset.eu/handle/20.500.12015/4140Modern online participatory platforms are a key tool for large-scale citizen participation, both concerning the number of citizens participating and their geographical distance. However, existing platforms implement little if any collaborative system in order to help people contribute. Consequently, my doctoral research questions the relevance of different types of collaborative editing systems as supports for citizen participation. Apart from that, I also propose an analysis of users’ behavior in a past online consultation in order to identify flaws and to draw recommendations concerning the design of participatory platforms.enText/Conference Paper10.18420/ecscw2021_dc0012510-2591
