Grouping of users

摘要

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for grouping of users. In one aspect, a method includes selecting a current user group for a search session based on search results selected by a user during the search session. The method also includes obtaining a plurality of search results responsive to a query submitted by the user during the search session wherein each of the search results has a respective score. The method also includes determining that a search result in the plurality of search results is one in which users associated with the current user group select as a selected search result a percentage of time more often or less often than a general population of users that is larger than a number of users associated with the current user group. The method also includes in response to determining, modifying an order of the plurality of search results by modifying the respective score of the search result based on the percentage. The method also includes providing the modified plurality of search results in response to the query.

1. A computer-implemented method comprising:
determining a user feature based on one or more query terms indicative of a particular feature that occur in a search query submitted during a search session; selecting a user group for the search session, of a plurality of user groups, wherein the user group is selected based on the determined user feature; obtaining a plurality of search results responsive to a second query submitted during the search session wherein each of the search results for the second query has a respective score indicating a quality measure of the result for the second query; determining that for one or more search results in the plurality of search results users associated with the selected user group select the one or more search results more often or less often than a general population of users that is larger than a number of users associated with the user group; based on the determining, modifying the respective score for each of one or more search results of the plurality of search results to create a modified plurality of search results, wherein the score for each of the one or more search results is modified based on, at least, the determination of how often the users associated with the selected user group select the search result relative to the general population; and providing the modified plurality of search results in response to the second query, wherein the modified plurality of search results has an order for presentation based on the respective scores and modified scores for the modified plurality of search results.
