摘要： A device includes a processor. The processor is configured to determine a hit time for each of a plurality of content items based on at least one of users' history of access to the content items on content distribution clusters in a content distribution network, the users' past ratings of the content items, and social network information associated with the users. The hit time of a content item indicates a number of times that the content item is likely to be accessed by the users. The processor is further configured to compute caching priorities of the content items based on a caching policy of the device and the determined hit times, and initiate a redistribution, over a network, of the plurality of content items over the content distribution clusters of the content distribution network based on the caching priorities.

摘要： The invention concerns a method and a server for routing between devices of a computer based social network having a plurality of users, wherein upon receipt of a first message from a device (110) associated with a user (u1), a second message is sent to another device (104, 110), wherein the other device (104, 110) is selected from a plurality of predetermined devices depending on the result of an evaluation of at least 1 trust value (S(c,u1;uM)) associated with the user (u1), a category (c) of content of the computer based social network and another user (uM) of the computer based social network.
摘要翻译：本发明涉及一种用于在具有多个用户的基于计算机的社交网络的设备之间进行路由的方法和服务器，其中在从与用户（u1）相关联的设备（110）接收到第一消息时，发送第二消息根据至少1个信任值（S（c，u1，uM））的关联的结果的结果，从多个预定的设备中选择另一设备（104,110）用户（u1），基于计算机的社交网络的内容的类别（c）和基于计算机的社交网络的另一用户（uM）。

摘要： A Bayesian Inference based recommendation system in a social network is provided. The method and system utilizes content ratings from a querying initiator's friends and their friends depending on the time to live (TTL) and other factors. Receiving users send to the querying initiator recommendation ratings from their friends and a conditional probability of distribution of the recommendation ratings given by the recommender's rooted at the friend. Once this information has been obtained from the friend/hopped friend network, the querying initiator's recommendation query engine constructs the QI's own rating response using the Bayesian Inference Network.
