Abstract:
1. A computer-implemented method, the method comprising: obtaining a model of typical behavior for each of a plurality of different statistics derived from selection data associated with each of a plurality of user identifiers, the selection data representing prior selections of search results by users associated with respective user identifiers, wherein the search results are responsive to respective search queries; determining a distribution of counts of deviations to counts of the user identifiers having those deviations, wherein a particular deviation is a calculated statistic for a user identifier that deviates from typical behavior for the statistic according to the model; determining a plurality of zones within the distribution of counts of deviations to counts of the user identifiers having those deviations, wherein each zone defines a respective range of deviations in the distribution; determining that a first user identifier of the plurality of user identifiers has a count of deviations that is within a particular zone of the plurality of zones within the distribution; and modifying, by one or more computers, selection data associated with the first user identifier based on a weight associated with the particular zone within the distribution in response to determining that the first user identifier has a count of deviations that is within the particular zone within the distribution.
