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: A method for restoring compressed data. A difference file and a reference file corresponding to a compressed file are accessed. The difference file is partially decompressed into a partially decompressed difference file in an intermediate representation. The reference file is partially decompressed into a partially decompressed reference file in the intermediate representation. A partially decompressed compressed file is generated based on said partially decompressed difference file and said partially decompressed reference file.

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 translation: 描述用于识别用户的一个或多个“兴趣双胞胎”的技术。 用户在其他用户中表现出与用户已经表现出兴趣的项目相同或类似的项目的兴趣的兴趣双胞胎。 描述了各种技术以减少感兴趣的双重确定操作的开销。 一旦已经识别出用户的兴趣双胞胎，感兴趣双胞胎的知识可以以各种方式用于增强用户的体验。 例如，可以提供允许用户查看用户兴趣双胞胎已经表示感兴趣的项目的列表的机制。

Abstract: Embodiments are directed towards a Modified Sequitur algorithm (MSA) using pipelining and indexed arrays to identify trending topics within a plurality of documents having user generated content (UGC). The documents are parallelized and distributed across a plurality of network devices, which place at least some of the received documents into a buffer for which the MSA may then be applied to the documents within the buffer to identify n-grams or phrases within the documents' contents. The identified phrases are further analyzed to remove extraneous co-occurrences of phrases, and/or words based on a part of speech analysis. A weighting of the remaining phrases is used to identify trending topic phrases. Links to content in the plurality of UGC documents that is associated with the trending topic phrases may then be displayed to a client device.

Abstract translation: 实施例针对使用流水线和索引数组来修改具有用户生成内容（UGC）的多个文档内的趋势主题的修改的序列算法（MSA）。 这些文档被并行化并且分布在多个网络设备上，这些网络设备将至少一些接收到的文档放置在缓冲器中，然后可以将MSA应用于缓冲器中的文档，以识别文档中的n个或多个短语， 内容。 进一步分析识别的短语，以消除基于词性分析的短语和/或单词的无关共存。 使用剩余短语的加权来识别趋势主题短语。 然后可以将与趋势主题短语相关联的多个UGC文档中的内容的链接显示给客户端设备。

Abstract: A query-centric system and process for distributing reverse indices for a distributed content system. Relevance ranking techniques in organizing distributed system indices. Query-centric configuration subprocesses (1) analyze query data, partitioning terms for reverse index server(s) (RIS), (2) distribute each partitioned data set by generally localizing search terms for the RIS that have some query-centric correlation, and (3) generate and maintain a map for the partitioned reverse index system terms by mapping the terms for the reverse index to a plurality of different index server nodes. Indexing subprocess element builds distributed reverse indices from content host indices. Routines of the query execution use the map derived in the configuration to more efficiently return more relevant search results to the searcher.

Abstract: A system comprises a plurality of computing resource. Attribute values for the computing resources are stored in a peer-to-peer network in the system. A method for storing an attribute value comprises receiving an attribute value for a resource in the system, identifying a node in the peer-to-peer network for storing the attribute value, wherein the node stores a range of attribute values encompassing the received attribute value, and storing the attribute value at the identified node.
