"Data coherence between OSM and WIkipedia"
Volunteered geographical information (VGI) are one facet of phenomenon of crowdsourcing in which people are collecting and sharing large amounts data in open and collaborative projects. Although these projects have different purposes and scopes there is some overlap between them so it can be asked if these data, which are collected from different communities with different processes, are coherent.
In this talk I will discuss a set of possile analysis between OSM and Wikipedia data, how they can be performed and a path for further research. I will also present some premilinary results of the application of these metrics regarding Italian Wikipedia and OSM in Italy for given category of objects (churches and historical buildings).
