Reverse IP databases using data indicative of user location

A computer-readable hardware storage medium comprising computer-executable instructions that when executed by a hardware processor enable updating a database, cause the processor to perform acts of:

• accessing a query log of a search engine configured to store queries made by users and IP addresses of the users;
• extracting location data related to the queries;
• aggregating most-frequently-used location data per IP address;
• updating an existing reverse IP database with updates to create an updated reverse IP database for use with a communications network based on the most-frequently-used location data;
• evaluating the updated reverse IP database against a ground-truth database to determine an accuracy of the updated reverse IP database for a particular range of IP addresses;
• determining, based on the evaluating, whether the updated reverse IP database is more accurate for the particular range of IP addresses than the existing reverse IP database;
• and
• only upon determining that the updated reverse IP database is at least a predetermined amount more accurate for the particular range of IP addresses than the existing reverse IP database, using the updated reverse IP database to determine a geographic location for particular range of IP addresses.

A system for updating a database, comprising:

• at least one processor;
• memory, operatively connected to the at least on processor, and storing instructions that, when executed by the at least one processor, cause the at least one processor to perform a method, the method comprising:
• accessing geographic location data indicative of user geographic location as derived from user actions;
• aggregating most-frequently-used location data per network address into aggregated database updates;
• updating an existing reverse IP (Internet protocol) database with the aggregated database updates to create an updated reverse IP database based on the most-frequently-used location data;
• evaluating the updated reverse IP database against a ground-truth database to determine an accuracy of the updated reverse IP database for a particular range of IP addresses;
• determining, based on the evaluating, whether the updated reverse IP database is more accurate for the particular range of IP addresses than the existing reverse IP database;
• and
• only upon determining that the updated reverse IP database is at least a predetermined amount more accurate for the particular range of IP addresses than the existing reverse IP database, using the updated reverse IP database to determine a geographic location for particular range of IP addresses.
