Querying geo-social data by bridging spatial networks and social networks

Abstract: Recording the location of people using location-acquisition technologies, such as GPS, allows generating life patterns, which associate people to places they frequently visit. Considering life patterns as edges that connect users of a social network to geographical entities on a spatial network, enriches the social network, providing an integrated sociospatial graph. Queries over such graph extract information on users, in correspondence with their location history, and extract information on geographical enti… Show more

“…For example, in SSNQL one can formulate a query that finds friends of Marge who frequently buy at the same grocery store as she does. SSNQL has first been formally introduced in [1], and it was extended in [2] to handle travel routes, however, it was prior to the development and implementation of a complete data management system. In this paper we present a fullfledged system that manages socio-spatial networks and supports the evaluation of SSNQL queries over an SSN.…”
