Abstract

The described technology is generally directed towards digital map truth maintenance. Map inputs shared among multiple users of a shared overlay map service can have a range of credibility, from not credible to highly credible. The disclosed digital map truth maintenance technologies can be used to enhance credibility of shared map inputs. Credibility values can be calculated for map inputs, based on any of multiple factors. Map inputs having sufficiently high credibility, such as a credibility value determined to be above a threshold value, can be shared among multiple mobile devices.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a device comprising a processor, a map input from a user equipment, the map input comprising a map location and description information associated with the map location;
determining, by the device, a map input credibility value for the map input, wherein the map input credibility value is determined based on an identity associated with the user equipment;
in response to the map input credibility value being determined to be above a first threshold value, determining, by the device, a representative map input based on the map input and at least one other map input other than the map input;
assigning, by the device, a representative credibility value to the representative map input, wherein the representative credibility value is based on the map input credibility value and at least one other map input credibility value of the at least one other map input; and
in response to the representative credibility value being determined to be above a second threshold value, sending, by the device, the representative map input to multiple user equipment devices.

2. The method of claim 1 , wherein the map input credibility value is determined based on proximity of a location of the user equipment with the map location included in the map input.

3. The method of claim 1 , wherein the map input credibility value is determined based on a time difference between a first time included in the description information and a second time associated with a transmission of the map input.

4. The method of claim 1 , wherein the identity is a first identity, and wherein the map input credibility value is determined based on whether the first identity associated with the user equipment matches a second identity accessible by the device.

5. The method of claim 4 , wherein the map input credibility value is determined based on an identity credibility value assigned to the second identity accessible by the device.

6. The method of claim 5 , further comprising updating, by the device, the identity credibility value based on the map input credibility value.

7. The method of claim 1 , wherein the map input credibility value is determined based on an output of a comparison of the map input with profile information associated with the identity.

8. The method of claim 1 , wherein the representative map input is based on a consensus of the map input and the at least one other map input.

9. The method of claim 1 , further comprising sending, by the device, a monitoring request to at least one user equipment, wherein the monitoring request comprises a request for an update of the map input.

10. The method of claim 9 , further comprising:
receiving, by the device, from the at least one user equipment in response to the monitoring request, the update of the map input;
modifying, by the device, the representative map input in response to the receiving the update of the map input; and
sending, by the device, a modified representative map input to the multiple user equipment devices.

11. A device, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
receiving a first map input from a user equipment, the first map input comprising a map location and description information associated with the map location;
determining a first map input credibility value for the first map input, wherein the first map input credibility value is determined based on proximity of a location of the user equipment with the map location included in the first map input;
in response to the first map input credibility value being determined to be above a first threshold value, determining a representative map input based on the first map input and a second map input;
assigning a representative credibility value to the representative map input, wherein the representative credibility value is based on the first map input credibility value and a second map input credibility value of the second map input; and
in response to the representative credibility value being determined to be above a second threshold value, sending the representative map input to multiple user equipment devices.

12. The device of claim 11 , wherein the map input credibility value is further based on a time difference between a first time included in the description information and a second time associated with a transmission of the first map input.

13. The device of claim 11 , wherein the first map input credibility value is further based on an identity associated with the user equipment.

14. The device of claim 11 , further comprising updating, based on the first map input credibility value, an identity credibility value of an identity associated with the user equipment.

15. The device of claim 11 , wherein the representative credibility value comprises an average of the first map input credibility value and the second map credibility value.

16. The device of claim 11 , wherein the representative credibility value comprises a mean of the first map input credibility value and the second map credibility value.

17. A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
receiving a map input from a user equipment, the map input comprising a map location and description information associated with the map location;
determining a map input credibility value for the map input, wherein the map input credibility value is determined based on a time difference between a first time included in the description information and a second time associated with a transmission of the map input;
in response to the map input credibility value being determined to be above a first threshold value, determining a representative map input based on the map input and another map input other than the map input;
assigning a representative credibility value to the representative map input, wherein the representative credibility value is based on the map input credibility value and another map input credibility value of the other map input; and
in response to the representative credibility value being determined to be above a second threshold value, sending the representative map input to multiple user equipment devices.

18. The non-transitory machine-readable medium of claim 17 , wherein the map input credibility value is further based on an identity associated with the user equipment and a proximity of a location of the user equipment with the map location included in the map input.

19. The non-transitory machine-readable medium of claim 17 , wherein the operations further comprise modifying the representative credibility value based on an agreement between the map input credibility value and the other map input credibility value.

20. The non-transitory machine-readable medium of claim 17 , wherein the representative credibility value comprises an average or a mean of the map input credibility value and the other map credibility value.
