A search engine provides personalized rankings of search results. A user interest profile identifies topics of interest to a user. Each topic is associated with one or more sites, and a boost value, which can be used to augment an information retrieval score of any document from the site. Search results from any search are provided to the user, with a variable control of the ranking of the results. The results can be ranked by their unboosted information retrieval score, thus reflecting no personalization, or by their fully or partially boosted information retrieval scores. This allows the user to selectively control how their interests affect the ranking of the documents. |

1. A computer-implemented method comprising:
receiving, at a user device, a search results page that presents search results identified in response to a first search query,
wherein the search results page includes a first representation of a first ranking of one or more of the search results based on first ranking scores of the search results, and a second representation of a second ranking of one or more of the search results based on second ranking scores of the search results,wherein the first ranking scores are based on a first degree of influence of a topic of a user interest profile on an initial ranking of the search results,wherein the second ranking scores are based on a different second degree of influence of the topic of the user interest profile on the initial ranking of the search results,wherein the second ranking scores are different than the first ranking scores,wherein the second ranking scores include a boosted IR score for a second search result in the second search results, and the boosted IR score is determined by:
determining an initial information retrieval (IR) score for the second search result of the second search results, wherein the second search result identifies a resource on a site,determining that the site is associated with a topic-specific boost value for the topic, wherein the topic-specific boost value is based on a number of links to the site from one or more other sites that have been determined to be relevant to the topic, anddetermining the boosted IR score for the second search result using the topic-specific boost value; andwherein the search results page includes a user interface control that allows a user to select a degree of influence of the topic on the initial ranking of the search results; presenting the search results according to the first representation of the first ranking based on the first ranking scores; determining that a user selection of the user interface control of the search results page corresponds to the second degree of influence of the topic of the user interest profile on the initial ranking of the search results; and in response to determining that the user selection of the user interface control corresponds to the second degree of influence of the topic of the user interest profile on the initial ranking of the search results,
presenting the search results on the search results page according to the second representation of the second ranking based on the second ranking scores without resubmitting a search query to a search engine to obtain the search results. |
