An exemplary point-of-interest merging system accesses point-of-interest data records. Each point-of-interest data record includes data representative of a distinct set of features for a distinct point-of-interest. The merging system generates, based on the distinct sets of features of the point-of-interest data records, a graph data structure that includes the point-of-interest data records and weighted feature relationships interconnecting the point-of-interest data records. The merging system clusters, based on the graph data structure, the point-of-interest data records into subset groups of point-of-interest data records. The merging system generates one or more merged point-of-interest data records based on the clustered subset groups of point-of-interest data records.
