    摘要: A method and apparatus for utilizing a course skeleton for adaptive learning is provided. Based on student profile information and course goal information, a query is generated to dynamically determine which learning items should be presented to the student. The query, which is based on a particular learning goal, may differ from student to student, and therefore different students may be presented with different learning items to achieve the same learning goal. In addition, as new learning items is added to the learning item repository, the learning items returned by the query for a particular learning goal may change, even if the query used for the goal does not.

    摘要: Method and apparatus for a searchable data service are described. The searchable data service may be implemented as a Web service with a Web service interface that allows the storage of locators and other attributes associated with entities stored in a data store in a searchable index. The attributes may be expressed as {name, value} pairs. The interface may allow client applications to query the searchable index to retrieve locators for entities in the backend data store according to the attributes associated with each locator. Search speed may be automatically optimized using, for example, indexes, query planning, and parallelism. The searchable data service provides a searchable index and is not a data store per se. The searchable data service separates searching and indexing of data from the actual storage of the data.

    摘要: Method and apparatus for repartitioning and replication of a searchable index in a searchable data service. The searchable data service may provide a searchable index to a backend data store. The searchable index may be repartitioned, and a partition may be moved to another storage node, to allow the searchable index to grow beyond the limits of a single storage device. Repartitioning may also be performed to provide load-balancing of write requests. Partitions may be replicated across two or more storage nodes to provide redundancy, data durability, data availability and load balancing of read requests among the storage nodes and/or across data centers. In one embodiment, a lazy replication mechanism may be used in the replication of partitions. In one embodiment, replication may be performed using an anti-entropy protocol to replicate a partition, and a gossip protocol to update the replicated partition.

    摘要: A system for backend conversion attribution of an advertisement served to a user device. The advertisement server provides an advertisement to the user device. The advertisement server receives user information from the user device. The advertisement server stores attributable event information and the user information into an attributable event record in a data store. Based on a user event, a conversion server receives conversion information and the user information from the user device. The conversion server stores the conversion information and the user information into a conversion record in the data store. An attribution server matches the attributable event record with the conversion record.
