Semantic Trails Datasets

This page contains the Semantic Trails Datasets (STDs) created from two different collections of check-ins obtained from the Foursquare platform.<br>The check-ins have been preprocessed in order to remove suspicious or erroneous check-ins. We constructed the semantic trails by grouping check-ins close in time and by adding various semantic information.<br>In details, the resulting files have the following fields: <i>trail_id</i>, <i>user_id</i>, <i>venue_id</i>, <i>venue_category</i>, <i>venue_schema</i>, <i>venue_city</i>, <i>venue_country</i>, and <i>timestamp</i>.<br>The <i>user_id</i> is a numeric identifier and it has been anonymized. The <i>venue_id</i> corresponds to the Foursquare URI of the venue and, therefore, it can be used to obtain additional information. The <i>venue_category</i> is a category from the Foursquare taxonomy, while the <i>venue_schema</i> is the corresponding Schema.org term. The <i>venue_city</i> is the Wikidata entity corresponding to the city in which the venue is located, while the <i>venue_country</i> is the Country associated with the city. Finally, the <i>timestamp</i> is expressed in the ISO 8601 format and it has been approximated to the minute.<br>
