Abstract: A social networking system provides suggestions of gifts to users for presentation to a target user for a life event of the target user. Merchants provide bids for their products. The social networking system selects products as gift suggestions based on the merchants' bids, recipient's interests, and the candidate user to whom the gift is suggested. The selected gift and any messages relating to the life event are held until a specified time and then delivered to the target user. At the time of delivery, the target user may be provided with alternative products that the target user can select instead of the gift. The social networking system can earn revenue based on promotion of products as gift suggestions, promotion of products as gift alternatives, and for any financial transaction related to the gift.

Abstract: A system indirectly infers concepts associated with a document. The concepts may be indirectly inferred based on information that does not include characteristics of the document, such as the characteristics that include a textual content of the document not associated with links included in the document, a domain of the document, and the document's Uniform Resource Locator (URL). The system may label the inferred concepts as useful to an audience of the document.

Abstract: IP address-user number estimates may be determined by accepting IP address usage information associating various IP addresses with various client identifiers, and generating an estimate of a number of users for at least one of the IP addresses using the IP address usage information. If the client identifiers include cookies, the estimate of a number of users for at least one of the IP address can be generated by determining a number of cookies for the at least one IP address for a given period of time, and multiplying the number by a second, predetermined, ratio of a number of users per cookie for the given time period. Other user identifying information includes user-agent parameters, browser parameters, and uncookied network traffic. The estimate of a number of users per IP address can be generated by determining a ratio of unique sets of user agent, browser parameters, and/or uncookied network traffic.

Abstract: A system and method for providing a graphical document are provided. A graphical document is processed to identify one or more ideas associated with the graphical document. The identified ideas may be used to determine concepts to associate with the first electronic document and suggest those concepts for association with the first electronic document for use in a document distribution system that distributes documents based on a price parameter associated with concepts and a performance parameter. A request for a document associated with a concept is received. Responsive to the request, the graphical document is delivered if an association between the one or more ideas and the concept is determined.

Abstract: A demographic attribute value of a sink online document (such as Websites or Web pages) may be determined given a set of users who have visited at least one of the source documents and the sink document, by (a) accepting a value(s) of the demographic attribute, each of which values is associated with a source online document (where each of the source online documents has a value for the demographic attribute and has been visited by at least one user of the given set), (b) determining an estimate of the demographic attribute value of each of the users of the given set using the accepted demographic attribute value of each of the source online documents visited by the user, and (c) determining the demographic attribute value of the sink online document using the determined estimate of the demographic attribute value of each of the users of the given set.

Abstract: A reservation system receives placement inventory data from publishers that define placements that the publishers are offering for reservation. Placement queries that include targeting criteria for advertisements are received from an advertiser. Available placements that satisfy the target query from the placements defined in the placement inventory data are identified as target placements. The advertiser can reserve the placements from the publisher, and modify the reservation during a reservation period. Advertisements belonging to a campaign of the advertiser can be provided to the publisher either by the advertiser directly in response to publisher requests to serve an advertisement for the reservation, or can be provided to the publisher by the reservation system or an advertising server in communication with the reservation system.

Abstract: A content owner partner (e.g., a Website/Web page publisher) can easily block entire broad or narrow categories of ads, and can specify objectionable ad content or targeting. Concepts may be associated with a property and ads related to those concepts may be blocked for the given property. Further, terms may be associated with a property and ads including any of the terms may be blocked for the given property.

Abstract: Methods, systems and apparatus, including computer program products, for generating cookies. Multiple advertisements for multiple advertisers are stored on an ad server. Hostnames specific to each of the multiple advertisers are generated dynamically. The generated hostnames identify the ad server. A reference is generated identifying a particular advertisement of the multiple advertisements and the ad server. The ad server is identified in the reference with the generated hostname associated with the advertiser of the advertisement. The reference is provided to a client. A request is received from the client for the advertisement. The request includes the generated hostname. In response to the request, a client cookie, which includes a unique identifier, is sent to the client.

Abstract: A communication icon represents a shared connection allowing members of an online group to interact with each other and participate in different activities together. The icon through which the group interacts resides on each group member's desktop and has many attributes including click activation modes and drag and drop functionality. The icon provides each group member with a representation of the group's shared relationship. Any group member can change the group icon and have that change propagated to the computers of the other members of the group. The icon can be activated for both non-verbal and verbal communications as well as activity sharing. Online members of the group are kept apprised of the group's status and activities via a displayed status bar.

Abstract: A demographic attribute value of a sink online document may be determined by (a) accepting a value(s) of the demographic attribute of a source online document, (b) accepting, for each of the source online documents having an accepted demographic attribute value, a probability that a user will visit or has visited the sink online document if the user visited the source online document, and (c) determining the demographic attribute value of the sink online document using the demographic attribute value of each of the source online documents and the probabilities. A demographic attribute value of the sink online document may also be determined using the above information and using the demographic attribute value of each of the source online documents and the probabilities that a user will visit or has visited the sink online document if the user visited the other online document.

Abstract: A method and system for allowing a resource associated with a target document usable for ad rendering by a first entity to be used for rendering of content by a second entity. Depending on one or more conditions, the first entity either uses the resource to render at least one ad or allows a second entity to use at least a portion of the resource to render content.
