Ulle Endriss, Umberto Grandi and Théo Delemazure participated to an event at the Dagstuhl castle in Germany on the societal impacts of research in computational social choice. The seminar attracted about 40 researchers from Europe and the US and featured talks on five broad topics: participation, societal impacts, restricted preference domains, data, and time in social choice processes. Five working groups were formed, with the aim to shape and inform the research agenda in the field, including a working group on the role of text processing algorithms such as large language models in social choice processes which was particularly relevant for the ADDI research agenda.
