Abstract:
1. A computer-implemented method comprising: receiving a search result obtained in response to a query, wherein the search result identifies a resource and has an associated score S; determining a query value Q for the query, the query value Q being based on a maximum of one or more query freshness signals, the query value Q representing whether users prefer newer resources over older resources for the query; determining a resource value D for the resource, the resource value D being based on a function of an age of the resource F(age), wherein F(age) represents whether the resource is a new resource; calculating a new score S′ as a product of S and a boosting function, the boosting function being a function of the query value Q and the resource value D, wherein S′>S whenever the query value Q indicates that users prefer newer resources over older resources for the query and F(age) indicates that the resource is a new resource; and associating the new score S′ with the search result in place of S.
