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 translation: 本发明涉及用于浏览由用户或由与给定用户相关联的一个或多个伙伴保存的内容项目的集合的系统，方法和用户界面。 本发明的方法包括保存由用户指定的一个或多个内容项和一个或多个关联关键字。 生成一个界面，显示一个或多个保存的内容项目以及一个或多个关联关键字，以及与给定用户相关联的一个或多个伙伴。 接收给定关键字的选择的用户指示或用户对给定好友的选择。 一个或多个显示的内容项目根据所选择的关键字，好友或所选关键词和伙伴的组合进行过滤。

Abstract: Techniques are provided for selecting a diverse mix of content items that may be displayed to a user. Content items such as user-generated events are received from a variety of sources. One or more content items are added to a set of content items based on a diversity of characteristics. The diversity of characteristics for the one or more content items may be calculated by measuring a diversity of characteristics of the set as if the one or more content items were added to the set. Content items that produce a greater diversity are selected for addition to the set. The set is displayed to the user, who is provided with a more meaningful mix of content due to the greater diversity in content.

Abstract: Techniques are described for identifying items that have recently undergone an interest burst. Items that have recently undergone an interest burst are identified by comparing how many interest-actions have been performed on the items during a current time window against how many interest-actions have been performed on the items historically. Various tests are performed to rule out candidates that are not likely to be of interest to other users. In addition, various spam detection techniques are described for reducing the possibility that the items that are listed as interest burst items are listed because of spam.

Abstract translation: 描述了用于识别最近经历了兴趣突发的项目的技术。 最近经历了兴趣突破的项目通过比较在当前时间窗口内对项目执行了多少兴趣操作来反映在历史上对项目执行了多少个兴趣操作来识别。 执行各种测试以排除不太可能对其他用户感兴趣的候选人。 另外，描述了各种垃圾邮件检测技术，用于减少由于垃圾邮件列出列为兴趣突发项目的项目的可能性。

Abstract: Embodiments are directed towards modifying a distribution of writers as either a push writer or a pull writer based on a cost model that decides for a given content reader whether it is more effective for the writer to be a pull writer or a push writer. A cache is maintained for each content reader for caching content items pushed by a push writer in the content writer's push list of writers when the content is generated. At query time, content items are pulled by the content reader based on writers a content reader's pull list. One embodiment of the cost model employs data about a previous number of requests for content items for a given writer for a number of previous blended display results of content items. When a writer is determined to be popular, mechanisms are proposed for pushing content items to a plurality of content readers.

Abstract translation: 实施例旨在基于决定给定内容读取器的成本模型来将作者的分布修改为推送写入器或拉写入器，以使作者是更有效的作为拉写入器还是推动写入器。 为每个内容读取器维护高速缓存，用于在生成内容时缓存内容写入者的推送列表中的推送写入器推送的内容项目。 在查询时，内容读取器根据写入者提取内容读取器的列表。 成本模型的一个实施例使用关于给定写入器的先前数量的内容项的请求的数据用于多个内容项的先前混合显示结果。 当作者被确定为流行时，提出将内容项推送到多个内容阅读器的机制。
