6. The electronic system of claim 1 , wherein the hardware processor is further configured to, in order to determine the score:

calculate a plurality of logarithmic values, each based on one of the plurality of initial scores; and

sum together the plurality of logarithmic values.

7. The electronic system of claim 6 , wherein the plurality of logarithmic values are each further based on a weighting factor corresponding to a time slot of a respective one of the plurality of initial scores.

8. The electronic system of claim 1 , wherein the hardware processor is further configured to:

determine first cardinalities of first-type device IDs and second cardinalities of second-type device IDs, each of the first cardinalities and each of the second cardinalities corresponding to one of the plurality of time slots, wherein

the plurality of initial scores are determined based on the first cardinalities and the second cardinalities.

9. The electronic system of claim 1 , wherein the hardware processor is further configured to, in response to the confirmation that the first-type device ID and the second-type device ID both identify the same device, link the second-type device ID with a user profile of a user of the same device, wherein the user profile was already linked to the first-type device ID prior to the confirmation.

10. The electronic system of claim 9 , wherein after the linking, the hardware processor is further configured to:

in response to receipt of user information associated with the second-type device ID:

identify the user information as being associated with the user; and

add the user information to the user profile.

11. The electronic system of claim 9 , wherein the user profile comprises a first user profile, and wherein the hardware processor is further configured to combine a second user profile associated with the second-type device ID with the first user profile to form an aggregated user profile for the user of the same device in response to the linking.

12. The electronic system of claim 9 , further comprising:

a content server configured to:

after the linking, receive a content request identifying user information associated with the second-type device ID; and

select content for sending to the same device, wherein the selection is based on user information that was initially added to the user profile prior to the linking.

13. The electronic system of claim 1 , wherein the hardware processor is further configured to:

receive visitor information indicating a user visited a network location, the visitor information identifying at least one of the first-type device ID or the second-type device ID;

in response to receipt of the visitor information, apply at least one of the first-type device ID or the second-type device ID to the device ID group database; and

update a visitor count based on the link between the first-type device ID and the second-type device ID in the device ID group database.

14. The electronic system of claim 1 , wherein the first-type device ID is associated with at least one of a web browser or an application, and the second-type device ID is associated with at least one of a second web browser or a second application, at least one of the web browser or the application and at least one of the second web browser or the second application being configured to run on the same device.

15. A method comprising:

preliminarily determining that a first-type device identification (ID) and a second-type device ID identify a same device;

grouping the first-type device ID and the second-type device ID into a device ID group in response to the preliminary determination;

determining a plurality of initial scores for the device ID group, wherein each of the plurality of initial scores is determined for at least one of a plurality of time slots associated with the device ID group and a network address;

calculating a score for the device ID group based upon the plurality of initial scores;

confirming that the first-type device ID and the second-type device ID both identify the same device based on the score; and

storing the first-type device ID and the second-type device ID as linked together in a device ID group database in response to the confirmation.

16. The method of claim 15 , wherein the preliminarily determining that the first-type device ID and the second-type device ID identify the same device is based upon a determination that the first-type device ID and the second-type device ID are both associated with a same network address.

17. The method of claim 15 , wherein the preliminarily determining that the first-type device ID and the second-type device ID identify the same device is based upon a determination that the first-type device ID and the second-type device ID are both associated with a same time slot.

18. A non-transitory computer readable storage medium comprising instructions that, when executed by a hardware processor, implement operations comprising:

preliminarily determining that a first-type device identification (ID) and a second-type device ID identify a same device;

grouping the first-type device ID and the second-type device ID into a device ID group in response to the preliminary determination;

determining a plurality of initial scores for the device ID group, wherein each of the plurality of initial scores is determined for at least one of a plurality of time slots associated with the device ID group and a network address;

calculating a score for the device ID group based upon the plurality of initial scores;

confirming that the first-type device ID and the second-type device ID both identify the same device based on the score; and

storing the first-type device ID and the second-type device ID as linked together in a device ID group database in response to the confirmation.

19.
