Updating Point of Interest Data Using Georeferenced Transaction Data

摘要

Georeferenced transaction data is harvested (“crowd-sourced”) from client devices and sent to a network-based map service. The map service performs cluster analysis on location data points in the harvested data, resulting in one or more clusters representing local densities of transaction occurrences. Data vectors including supplemental data are obtained from one or more vendors. Location data points included in the data vectors are compared to center coordinates of the one or more clusters and the closest matching cluster/vector pair provides a mapping to POI data in a POI database. The mapped POI data is updated with the supplemental data. In some implementations, transaction timestamps in the harvested data are used to estimate the business hours of a business POI.

1. A method comprising:
receiving, at a network-based service, georeferenced transaction data harvested from wireless devices during transaction events; performing cluster analysis on the georeferenced transaction data, the cluster analysis resulting in one or more clusters associated with the georeferenced transaction data; mapping supplemental data to one of the one or more clusters; and updating point of interest (POI) data with the supplemental data, where the method is performed by one or more hardware processors.
