Abstract: A method performed by one or more computing devices. The method uses data identifying a plurality of users and a plurality of achievements. The data identifies which of the plurality of achievements each of the plurality of users has earned and when any such achievements were earned. The method includes ordering the plurality of achievements to define an ordered achievement list, and for each of the plurality of users, removing from the ordered achievement list any of the plurality of achievements identified in the data as having been earned by the user to define a recommended achievement list for the user. The method also includes identifying a selected achievement, and identifying as a set of similar users any of the plurality of users whose recommended achievement list includes the selected achievement.

Abstract: A method performed by one or more computing devices. The method uses data identifying a particular user of a plurality of users, a title, and a plurality of achievements that may be earned with respect to the title. The data identifying which of the achievements the particular user has earned. The method includes determining an achievement difficulty value for each of the achievements, determining a title interest contribution value for each of the achievements as a function of the achievement difficulty value determined for the achievement, identifying one or more of the achievements that were earned by the particular user, and determining a user interest value as a function of the title interest contribution value determined for each of the identified one or more of the achievements (earned by the particular user). The user interest value indicates a level of interest of the particular user with respect to the title.

Abstract: Embodiments of the present invention relate to systems, methods and computer storage media for facilitating the structured storage of binary large objects (Blobs) to be accessed by an application program being executed by a computing device. Generally, the structured storage of Blobs includes a primary structured storage index for indexing Blobs, a secondary hash index that is integrated into the structured storage system, a Blob log stream, and a Blob data stream for storing blocks that include the Blob data. In an embodiment, a block is created and written to a Blob store along with a block list. The block list facilitates the locating of one or more blocks that store the Blob data. In this embodiment, a primary structured storage index and a secondary hash index are updated to facilitate efficient access of the Blob in a structured storage system.

Abstract: Embodiments of the present invention relate to systems, methods and computer storage media for facilitating the structured storage of binary large objects (Blobs) to be accessed by an application program being executed by a computing device. Generally, the manipulation of Blobs in a structured storage system includes receiving a request for a Blob, which may be located by way of a Blob pointer. The Blob pointer allows for the data, such as properties, of the Blob to be identified and located. Expired properties are garbage collected as a manipulation of the Blob data within a structured storage system. In an embodiment, the Blob is identified by a key that is utilized within a primary structured index to located the requested Blob. In another embodiment, the requested Blob is located utilizing a secondary hash index. In an additional embodiment, the Blob is locate utilizing a file table.
