eParticipation projects often comprise deliberation among participants, where proposals are collected, discussed and rated to be processed in further stages of the eParticipation. In the case of large-scale audiences, this initial stage involves mass-online deliberation (MOD), which has to cope with a potentially very large number of proposals advanced by the participants. To enable clustering, MOD rely on human- (i.e. participant)-based appraisals of proposals given in the course of the participation project. Based on these appraisals, this contribution then proposes a clustering algorithm that makes use of the whole set of the above individual ratings. (Dis-)approval ratings are first weighted by the indication of clarity, that is, the higher the clarity rating assigned by a person, the higher the weight with which the (dis)approval rating will enter the clustering.
