Abstract: Techniques are described for identifying one or more “interest twins” of a user. An interest twin of a user in another user that has demonstrated interests in items that are the same as or similar to the items in which the user has demonstrated an interest. Various techniques are described for reducing the overhead in interest twin determination operations. Once the interest twins for a user have been identified, the knowledge of the interest twins may be used in a variety of ways to enhance to experience of the user. For example, a mechanism may be provided which allows the user to see a list of items in which the user's interest twins have indicated an interest.

Abstract: In a method of mapping peers in a peer-to-peer network to an overlay network, network coordinates are determined for a selected peer. The logical coordinates in the overlay network are determined based on the network coordinates. A zone is determined based on the logical coordinates. The network coordinates, a network address of the selected peer and the zone is stored as an object at a peer owning the zone, where associated information is stored in the peer that has the network coordinate and using the network coordinate as a key.

Abstract: The present invention relates to systems, methods, and user interfaces for browsing a collection of content items saved by a user or by one or more buddies associated with a given user. The method of the present invention comprises saving one or more content items and one or more associated keywords as specified by a user. An interface is generated that displays the one or more saved content items and the one or more associated keywords, as well as the one or more buddies associated with a given user. A user indication of the selection of a given keyword or the selection of a given buddy by the user is received. The one or more displayed content items are filtered according to the selected keyword, buddy, or combination of selected keyword and buddy.

Abstract: A network includes a plurality of nodes. A set of candidate nodes from the plurality of nodes is selected based on location information for the candidate nodes and a first node also in the network. A clustering algorithm is applied to the location information for the candidate nodes and the first node, and a subset of the set of candidate nodes closest to the first node is identified based on the results of applying the clustering algorithm.

Abstract: Access control systems and methods regulate access to shared content items in a corpus using visibility tokens. A user provides other users with access to a content item by associating a content token with the content item and associating a matching user token with each user who is to be granted access. A user who attempts to access the content item succeeds only if that user has a user token matching the content token associated with the content item. User tokens can be propagated automatically from one user to another, e.g., based on trust relationships among the users. Content tokens can be indexed with content items so that when a user searches the corpus, a search engine can detect matches between user tokens and content tokens and filter the search results based on whether they are visible to the querying user.

Abstract translation: 访问控制系统和方法使用可见性令牌来规范对语料库中共享内容项的访问。 用户通过将内容令牌与内容项相关联并将匹配用户令牌与要被授予访问权限的每个用户相关联来向其他用户提供对内容项的访问。 仅当该用户具有与内容项相关联的内容令牌匹配的用户令牌时，尝试访问内容项的用户才能成功。 用户令牌可以自动地从一个用户传播到另一个用户，例如，基于用户之间的信任关系。 内容令牌可以用内容项目索引，以便当用户搜索语料库时，搜索引擎可以检测用户令牌和内容令牌之间的匹配，并根据查询用户是否可见筛选搜索结果。

Abstract: An overlay network is used to logically represent an underlying physical network. A network condition is monitored by a node in a target region of the network. If the network condition occurs, the node transmits a notification to a source node including location information for nodes physically close in the physical network. The source node may select a routing node in the target region based on the location information.
