Activity-related data associated with a subject entity is obtained. Weight values are assigned to portions of the obtained activity-related data, wherein the weight values range between a low entity location-predictive weight value to a high entity location-predictive weight value, and wherein the portions of obtained activity-related data form a plurality of data paths. The assigned weight values are added along each data path of obtained activity-related data to compute a plurality of data path weight values. A past, present and/or future location of the subject entity is determined based on a selection of one of the plurality of data path weight values. For example, the location associated with the data path with the highest data path weight value is selected as the location of the subject entity.
