A lot of content has been produced with crowdsourcing by Wikimedia users, not only on Wikipedia. Hundreds of thousands of photographs of cultural heritage were uploaded in the last 20 years and are available on Wikimedia Commons, still not linked to structured data on Wikidata, often of unknown historical buildings, like ruined churches in Southern Italy. We will demonstrate that is possible to use data mining techniques on Wikimedia projects and build on Wikidata a more comprehensive open catalogue of Cultural heritage in Italy from crowdsourced contents. We will present the result of phase 1 and 2 of this project, where OpenRefine was used to create thousands of new items on Wikidata about "lost heritage" in Italy, and discuss of the possible use of AI to speed-up the process.
