The CIVIC EPISTEMOLOGIES project investigates citizen science and crowdsourcing in the domain of the research in Digital Cultural Heritage and Humanities. The ultimate aim is to produce a validated Roadmap indicating the suggested direction that the deployment of services and infrastructures should take, in order to support the participation of citizens in the research processes and the participation of creative industries in the exploitation of digital cultural content. The case of DCHH is particularly relevant because of the major cross-cutting role (...) that the humanities play in European research and innovation, recently acknowledged in a clear way in the Horizon2020 Community Programme for Research and Innovation. Cultural heritage and humanities also represent a subject area in which citizens are particularly active, counting several? still spread - experiences of their involvement in recording, annotating and cataloguing activities on an individual or group basis, as volunteers and amateurs. The case of broadening e-Infrastructure deployment to support the participation of citizens to DCHH research, even if holding a strong impact potential for social cohesion and job development, is not yet fully explored. The paper discusses about the multidisciplinary approach to citizen science and how this method can contribute to the benefit of many scientific domains, research communities, and technology advancements as well as delivering novel social and economic impact.
