Currently, Digital Democracy is gaining momentum thanks to online participation platforms, which have emerged as innovative tools that enable citizens to participate in decision making processes. Through these tools, participants can issue proposals and engage into debates by both stating arguments in favour or against and/or by supporting other people’s arguments. In this paper we propose a new support aggregation method derived from the combination of two complementary aggregation methods previously introduced. Additionally, we propose a resilience metric for measuring the quality of the aggregated opinion. We apply our contributions to debates conducted in the Decidim participatory platform.
