In this project, a completely new infrastructure for the Humanities is developed for the exploitation of documentary sources (like images and retro-digitized text) as well as for the retrieval of empiric sources (like forms of speech). Over different web platforms, operated by the same social software, games with a purpose (GWAP) should engage a broad audience with the exploitation of sources or the retrieval of empiric sources. Two representative cases have been chosen for the beginning of the project: The first web platform should help exploiting images for Art History, the second collecting field data on the Italian language. It is planned to employ the infrastructure, which is being developed during the project, in further subjects. The project is the outcome of a long lasting cooperation between humanists, computer scientists and computational linguists. It is relevant for research for all participating subjects.
