Abstract:
1. A computer-implemented method comprising: receiving a user-submitted query; generating an initial ranking of one or more documents responsive to the user-submitted query, the one or more documents including a first document responsive to the user-submitted query; determining that the user-submitted query does not match any record in a model of queries and documents, the model comprising a plurality of records, each record specifying an association between a respective model query, a respective model document, and respective click data aggregated for all users that select the respective model document in response to the respective model query; in response to determining that the user-submitted query does not match any record in the model, forming one or more variants of the user-submitted query to generate one or more other queries that each match a respective record in the model, each of the one or more other queries being different from the user-submitted query; deriving a generalized quality of result statistic for the first document responsive to the user-submitted query from respective data associated in the model with one or more of the other queries, wherein: providing the generalized quality of result statistic as input to a subsequent document ranking process for the user-submitted query that generates, using the generalized quality of result statistic for the first document responsive to the user-submitted query, a subsequent ranking of the one or more documents responsive to the user-submitted query.
