摘要： A testing materials production system generates a testing document associated with an electronic foundation document. The testing materials production system automatically generates the testing document by populating regions of a template with testing elements extracted from the electronic document. User customizations of the testing document are received, and the testing document is published to an extended catalog database associated with the electronic document. Regions of the testing document may be delivered in association with the electronic document to designated recipients via browser applications executing on computing devices of the recipients.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing personalized avatars for virtual companionship are disclosed. One of the methods includes capturing one or more current online activities of a user of an online education platform providing learning services to the user; receiving sensor data from one or more electronic devices of the user; detecting an event by analyzing a combination of the one or more captured online activities of the user and the received sensor data; determining one or more avatars and one or more special effects associated with the one or more avatars based on the detected event and one or more pre-determined rules mapping avatars and special effects to events; generating multimedia content comprising the one or more avatars and the one or more special effects; and streaming the generated multimedia content to a multimedia display device of the user.

摘要： A method of automatically providing personalized learning activities to users of an online learning platform is described. A quest is built based on an input of at least a first user's educational objective. The quest includes a primary quest that starts with a start node, ends with the end node, and includes a set of intermediate nodes, wherein each node of the primary quest must be traversed by the first user in order to complete the quest. The quest includes at least one secondary quest that starts with a node of the primary quest as its start node and includes a second set of intermediate nodes. As the user selects a node of the quest, educational activities related to its respective concept are presented to the user. The user's progress in the quest is tracked.

摘要： An online education platform manages and integrates a number of education services for users of the platform, including job recall services. These job recall services include management and distribution of job recall materials that test whether job applicants have acquired desired knowledge or skills for a particular job opening or class of jobs. The job recall materials are uploaded to the education platform and mapped to one or more learning units. Each learning unit is associated with an educational course and includes a distinct concept in the associated course. Responsive to a user of the education platform completing the learning unit to which a job recall material is mapped, the job recall material is recommended to the user.

摘要： A service control system controls access to secured online testing services, such as accredited or standardized tests, examinations in educational courses, tutoring services, and continuing professional development courses or seminars. The secured services may be published by an educational publishing platform and made available to users through online configured browser applications executing on the users' devices. Based on access conditions associated with a secured testing service and the capturing and processing of one or more images, the service control system determines how users are authorized to access the services. When users have been authorized to access a service or a subset of the service, the service may be distributed through the browser applications executing on the users' devices.

摘要： Employers or recruiters populate an online database with job postings. The concepts that job applicants need to have learned to be successful applicants for a job are stated or inferred from the job posting and optionally resumes of others who have held that job. A student's own learning activities are logged by an online education platform. From a comparison between the student's completed learning units and a job posting's required learning units, a personalized learning unit gap can be identified for a student. The online education platform can then recommend how the student can fill the gap by undertaking the study of learning units on the education platform.

摘要： An online review system determines scores for document authors and document reviewers. An author score is based on a number of comments added to a document by reviewers. One way to compute the author score is to use a ratio of a number of comments provided by reviewers of a document to a number of lines of document contents provided by the author. A reviewer score for a reviewer is based on an amount of comments subsequently made by other reviewers, and on the document content itself, such as a ratio of a number of comments provided in subsequent reviews of a document to a number of lines of original document contents. In some embodiments, the online review system monitors trends in scores of individuals or teams.
