Abstract: In one embodiment, a method includes identifying and recursively populating a geographic tile with entities. Recursively populating a geographic tile with entities includes: sending a request to a third-party server for entities located near a representative point of the geographic tile; calculating a maximum distance from the representative point among the entities received; and determining whether a bounding perimeter based on the maximum distance encompasses the geographic tile. If the bounding perimeter encompasses the geographic tile, the retrieved entities located within the geographic tile are stored in association with an identifier for the geographic tile. If the bounding perimeter does not encompass the geographic tile, the geographic tile is divided and the subdivision tiles are recursively populated.

Abstract: Systems, methods, and non-transitory computer-readable media can select a first sample set comprising one or more data elements from a dataset based on a first priority score ranking at a first time for a first analysis. A second sample set comprising one or more data elements from the dataset is selected based on a second priority score ranking at a second time for a second analysis. An evaluation subset of one or more data elements from the second sample set is determined based on a comparison of the first sample set and the second sample set. The data elements in the second sample set that are not included in the evaluation subset are not analyzed ni the second analysis.
