Patent ID: 8862492

Claim:
A method, executed by a computer system, for determining the unreliability of a user providing edits to an online map, the method comprising: analyzing interaction sessions of unreliable users with an online map editing service to identify session characteristics of the unreliable users; receiving a plurality of interactions by the user with the online map editing service; identifying a plurality of interaction sessions by the user based on a timing of the plurality of interactions; determining the identified characteristics for each of the plurality of interaction sessions by the user; determining by one or more processors a score for each determined characteristic; determining by the one or more processors using a model trained on the interaction sessions of unreliable users an unreliability score indicative of a probability that the user provides intentionally incorrect edits based at least in part on the determined scores of the determined characteristics; and responsive to the unreliability score exceeding a threshold, identifying the user as unreliable.
