Abstract: A novel application and user interface for facilitating group interactions over a network integrates messaging, file sharing, media playing, journaling, profiles, and gaming into a cohesive environment. The groups facilitated by the invention are persistent and mobile in that a user does not have to recollect and reconfigure the group each time he or she wants to interact with the group online and, while online, the group may be taken from one activity to another without having to disband and reconnect at the second activity. The application is modular so as to be extensible to include other activities and functionalities. In an embodiment, the group interaction application utilizes a peer-to-peer network environment to facilitate network communications between group members.

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: A novel virtual calling card system and method aid in the formation of online relationships, serving as an introduction tool and as a contact mechanism. The calling card is an exchangeable entity that is automatically updated, ensuring that the recipient or viewer sees the most current version of the card. The card may display an aspect ratio that is the same as that of a traditional business card, and has front side and a reverse side. Furthermore, the card provides a number of avenues for the card owner to express themselves, including an array of affiliation symbols, a most recent mood symbol, and a text field. The reverse side of the card can display a representation of the owner's social network, so that recipients of the card may identify common friends and associates. Thus, the server-based card exchange appears to users as an exchange in the physical world.

Abstract: A computer-implemented method includes determining an attribute of a web page to be displayed to a user at a location, selecting content corresponding to the determined web page attribute, and transmitting the selected content to the location for display as at least part of the web page.

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 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 price paid for an ad impression may be adjusted using an estimated probability that the ad will be viewed, or otherwise perceived or sensed, or using one or more factors which may be used to estimate such a probability. The price and/or probability may be adjusted using events occurring after the impression of the ad.

The exchange of the card, although server-based, appears to users to simply be a transfer of the card from the owner, or other party, to the recipient, much as a card changes hands in the physical world.

Abstract: The serving of ads of different ad types, such as text ads and image ads, competing to be rendered on an ad area of a document may be arbitrated by (a) determining candidate ads to serve in response to an ad request, wherein the candidate ads include at least one ad of a first ad type and at least one ad of a second ad type, (b) determining a score of each of at least some of the candidate ads, (c) comparing alternative sets of the at least some of the candidate ads to select a set that best meets at least one policy goal, and (d) serving the selected set of candidate ads. Performance parameter values of ads of one type, such as image ads for example, may be estimated from performance parameter values of ads of a second type, such as text ads for example.
