Recently, our group developed XOSM, a query language and visualization tool for OpenStreetMap. This paper describes how to integrate social network queries into the XOSM query language. As a consequence of such integration, XOSM enables the definition and visualization of queries in which social network data are retrieved for POIs. XOSM social network queries serve to analyze the characteristics and relevance of POIs by visualizing Twitter and YouTube data. XOSM APIs have been built on top of the social network APIs to map XOSM POIs to social network data. To obtain better ac...
