Navigational resources for queries

摘要

Methods, systems, and apparatus, including computer program products, for identifying navigational resources for queries. In an aspect, a candidate query in a query sequence is selected, and a revised query subsequent to the candidate query in the query sequence is selected. If a quality score for the revised query is greater than a quality score threshold and a navigation score for the revised query is greater than a navigation score threshold, then a navigational resource for the revised query is identified and associated with the candidate query. The association specifies the navigational resource as being relevant to the candidate query in a search operation.

1. A computer-implemented method, comprising:
selecting a candidate query in a query sequence stored in a query log, the query sequence including an initial query and one or more revised queries and defining an order in which the queries were submitted for a search session; selecting a revised query subsequent to the candidate query in the order; determining a probability of revision from the candidate query to the revised query; determining a probability of entry of the revised query; and determining that the probability of revision from the candidate query to the revised query is greater than the probability of entry of the revised query, and in response:
identifying a navigational resource for the revised query; andassociating the navigational resource with the candidate query, the association specifying the navigational resource as being relevant to the candidate query in a search operation.
