Abstract:
An online system maintains information identify a context in which sponsored content items were presented to users. A context in which a sponsored content item was presented to a user identifies additional content presented to the user prior to the sponsored content item, and may identify additional content presented in conjunction with the sponsored content item. The online system identifies users to whom at least one sponsored content item was presented in a context and generates characteristics for the context based on characteristics of users who were presented with at least one sponsored content item in the context. When the online system receives a request to present sponsored content items in the context that does not identify an online system user, the online system selects sponsored content items for the request based on the generated characteristics for the context.

Abstract:
In one embodiment, a method includes receiving a query form a client system of the first user. The method includes identifying one or more objects matching the query. At least one of the identified objects is an advertisement. The method includes calculating, for each identified advertisement, a score based at least in part on an affinity coefficient for the first node with respect to the second node corresponding to the identified advertisement. The method includes generating one or more search results corresponding to one or more of the identified objects matching the query, respectively. Each search result includes a reference to the corresponding identified object. At least one of the search results corresponds to an identified advertisement having a score greater than a threshold score. The method includes sending a search-results page including one or more of the generated search results to the client system for display.
