Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for ranking search results. One of the methods includes receiving a search result obtained in response to a query. A recent impression probability for the query for a recent time period and an overall impression probability for the query for an overall time period are computed. A ratio QtoA of the recent impression probability to the overall impression probability is computed. A determination is made that users prefer newer resources over older resources for the query based on QtoA and that the resource is a new resource. A new score S′ is associated with the resource in place of S, wherein the new score S′ signifies a better result than the score S signifies, based on determining that users prefer newer resources over older resources for the query, and that the resource is a new resource.
