Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing advertisements. In one aspect, a method includes receiving a request for an advertisement from a user device associated with a first user, and identifying advertisements responsive to the request. A determination is made that one of the advertisements describes a good or service that is associated with an endorsement provided by an endorser, and the endorser is recommended by a second user that belongs to a same social network as the first user. The advertisements are ranked based on one or more signals associated with each advertisement, wherein one of the signals for the one advertisement is the endorsement and is used in the ranking in response to the determination. The ranked advertisements are provided in response to the request.

Abstract: Various techniques are described for resource management on a computing platform. A computing platform can receive a query message that specifies an amount of a resource proposed for allocation. The computing platform can select a selected recommendation level from a plurality of recommendation levels, based on an evaluation of a request for the amount of the resource proposed for allocation. The computing platform can generate a resource allocation recommendation that includes the selected recommendation level with respect to the amount of the resource proposed for allocation. The computing platform can send the resource allocation recommendation.
