Abstract: Enabling an authenticated user to access content associated with an authenticated user as though the authenticated user had a selected user relationship with the authenticated user. The user relationship may comprise a relationship degree, a relationship category, a relationship rating, and/or the like. An invitation to join an electronic service, such as an online social network, is sent to the unauthenticated user at an address known to the authenticated user. The invitation includes a time-limited token, such as a URL, that includes an invitation identifier, which relates the invitation to the authenticated user content. The token may be encrypted in the invitation. The unauthenticated user returns the token as a request to preview the authenticated user content without first becoming an authenticated user of the electronic service. If the token is still valid, access is granted. The unauthenticated user may also request to establish a connection with the authenticated user.

Abstract: Enabling a content publisher and a receiving user to control access to content updates based on user relationships. The content publisher and the receiving user may assign a relationship degree, relationship category, and/or relationship rating to each other and to other users. The content publisher and/or receiving user also specify a required relationship that is needed to access or accept a content update. The content publisher and receiving user may further specify acceptable types of content updates, such as blog entries, product reviews, photos, and the like that are accessible or acceptable. Upon logon or other event, a summary of content updates is provided to each receiving user that meets each content publisher's required relationship, and the content updates are delivered according to a selected delivery method from those content publishers that meet the relationship requirements of the receiving users. Delivery includes email, instant message, RSS feeds, and the like.

Abstract: A method, apparatus, and system are directed towards seeding a user's contacts for their online social network. The invention is arranged to automatically recommend to the user a set of seed contacts that the user may employ to invite to join their social network. The set of seed contacts may be harvested from the user's existing portal activities, as well as other sources. In one embodiment, the invention analyzes portal activity, such as email exchanges with the user, and the like, to determine a frequency of contact with the user. Other sources may include but not be limited to emails, names within an address book of the user, names within an address book of another person, a buddy list, an instant messaging list, an activity, a mailing list, an online discussion group, a membership in a category, chat group, and the like.

Abstract: A system, apparatus, and method are directed towards enabling information filtering using measures of an affinity of a relationship between subscribers of an online portal system. The affinity of a relationship may be determined based, in part, on the tracking of various online behaviors of and between subscribers of the portal system. Any of a variety of behaviors may be tracked, including message communications between subscribers, participation in instant messaging groups, purchases, activities, categories, and so forth. Such behaviors may be employed to determine a level of trust (or affinity) between subscribers of the portal system. This affinity measurement may be used to filter various information, including, but not limited to, product recommendations, ratings, polling queries, advertising, social network communications, personal ads, search results, and the like. Moreover, this affinity measurement may also be employed to perform message spam detection.

Abstract: Enabling a first user to preview content as it would be seen by a second user, if the second user had a selected user relationship with the first user. The selected user relationship may include a relationship degree, a relationship category, a relationship rating, and/or other form of relationship. In one embodiment, a user interface enables the first user to assign user relationships to portions of content and to other users. The first user selects a user relationship, which is used to access those portions of content that are associated with the first user and assigned the selected user relationship. The corresponding portions of content are used to generate a preview display for the first user, illustrating the portions of content that would be accessible to other users assigned the same user relationship or assigned a closer user relationship. Preview may be generated by a server or a local client.

Abstract: A method, apparatus, and system are directed towards managing a view of a social network user's personal information based, in part, on user-defined criteria. The user-defined criteria may be applied towards a user's relationship with each prospective viewer. The user-defined criteria may include degrees of separation between members of the social network, a relationship to the prospective viewer, as well as criteria based, in part, on activities, such as dating, employment, hobbies, and the like. The user-defined criteria may also be based on a group membership, a strength of a relationship, and the like. Such user-defined relationship criteria may then be mapped against various categories of information associated with social network user to provide customized views of the social network user.
