摘要:
A target user's profile may be generated based on scanning metadata related to various content items made available for sharing by the user. For instance, some content items may be made available for sharing by the target user while other items are made available for sharing by one or more other users in the target user's social network. A list of keywords related to each item may be generated from the metadata. Each keyword may then be scored using social network data. For example, social network data corresponding to one or more users associated with each content item may be used to score keywords related to that item. Scoring may be based on factors such as social network distance, relationship type, trust, length of time in the social network, amount of content, amount of metadata, and other factors.
摘要:
A first user's trust level with regard to a second user can be determined by providing questions to the second user, with the questions based on a previously-collected knowledge base including information about the first user. The information about the first user may be partitioned into levels of trust, and the second user's responses to the questions may be evaluated to determine which level of trust the second user is entitled to. The knowledge base may be assembled by prompting the first user for information and/or by scanning or otherwise collecting already-existing data about the first user. The knowledge base and/or trust assessment may be distributed across a network, and in some embodiments the knowledge base or parts thereof is distributed to other users according to the trust level of those users.
摘要:
A controlled content distribution system (CCDS) employs a peer-level application into which a content producer can import digital content (e.g., video, audio, graphic, image, text, code files, etc.) The content producer identifies distribution parameters including an initial distribution list and a level limit representing the maximum number of levels, or degrees of separation for allowed distribution in a FOAF social network. Distribution parameters also include an alteration definition for one or more allowable levels in the network. Alteration definitions may identify a file degradation characteristic, file augmentation, or deletion parameter for altering the digital content from its original form. Alteration definitions often vary at each level. A distribution package is created by the CCDS and includes the digital content, a configuration data file, a key ID and a license key seed. The distribution package is processed at a FOAF license server before being sent to additional content recipients.

摘要:
A license server and corresponding method are provided for managing the rights of content as it is propagates through a social network. A license server receives a distribution package from a content producer and establishes a plurality of level-licenses, one for each of n allowable levels as defined by the content producer. Level-licenses define level-rights, or access rules, based on alteration definitions and other distribution parameters provided by the content producer for each allowable level. Alteration definitions may identify degradation characteristics or augmentation files for association with the distributed digital content. Content recipients who receive encrypted copies of the distributed digital content may request a license from the license server. Upon authentication, a license and decryption key is sent to a valid content recipient to enable viewing of a form of the digital content in accordance with the level-rights predetermined by the content producer for that level of access.
摘要:
An optimization server with associated databases for use in social networks utilizes previous interactions and other factors and parameters to optimize a user's level in a social network. The optimization server may be configured to proactively and/or reactively optimize a user's level in a social network by selecting previous social network instances, merging data from the selected instances into a single social network data representation, determining the shortest path between originating and recipient nodes in the network, and assigning a default level for the recipient node based on the shortest path. Additional optimization parameters may be applied to increase or decrease the recipient node's default network level (within certain optionally established limits for change). Various parameters that may be utilized to optimize the social network may include, but are not limited to, user parameters, content classification, user classification, distribution history, existing FOAF definitions, and other external data.

摘要:
A system and method are provided for accessing and managing information, or metadata, describing content residing on a number of agent devices. In general, the system includes a central node and a number of agent devices communicatively coupled by a network. In operation, the central node communicates with the agent devices to obtain content information describing content stored at the agent devices and optionally the locations of the agent devices from the agent devices. The content information and optionally the locations of the agent devices are stored in a database associated with the central node. Thereafter, the central node enables requesting nodes such as the agent devices to access the database. For example, the agent devices may communicate with the central node to obtain the content information for one or more known agent devices or to query the database to find agent devices having content information and optionally locations that satisfy specified criteria. In addition or alternatively, the central node may provide automatic alerts to the agent devices when other agent devices matching specified criteria are available.
摘要:
A system and method for generating a profile of communication sessions involves generating ratings for a selected set of messages and metadata associated with content items that are shared by social network users participating in a communication session. Ratings may be based on keyword scores which may then be adjusted based on user participation parameters, social network characterization parameters, and user selected options. Communication session profiles change over time and so recomputation is effected on periodic or scheduled bases. Generated profiles may be stored, frequently retrieved, or used in applications such as but not limited to content filtering, recommending content shared by participating social network members, selecting relevant advertisements, providing topic suggestions or user list invitations.
