Abstract: Techniques are described for controlling access to an online service by a one or more authentication mechanisms based on device, browser, or location, or a combination of the three. A method comprises receiving a request to access a service, receiving, in association with the request, a first access mechanism, receiving a first and second level of authentication associated with the user requesting the service, updating authenticated-mechanism data to indicate that the first access mechanism is an authenticated access mechanism for the particular user, receiving a second request to access the service, in response to receiving a second request, determining whether the second access mechanism is an authenticated access mechanism for the particular user, upon determining that the second access mechanism is not an authenticated mechanism, requesting a second level of authentication for the particular user, otherwise granting access.

Abstract: Resources available to a service node in a system are dynamically modified. The modification is based on current performance levels of other service nodes, application level transactions, resource utilization patterns, and/or in response to detecting a pre-failure conditions.

Abstract: A method and system are provided for generating a comprehension indicator that indicates how well an individual understood the subject matter covered by a test. In one implementation, a question-level comprehension indicator is generated for each of the questions on the test. The question-level comprehension indicators may be generated based upon one or more question-level factors, which may include behavioral aspects of the individual while taking the test. After the question-level comprehension indicators are generated, they may be used to generate a first test-level comprehension indicator. A second test-level comprehension indicator may also be generated. Unlike the first test-level comprehension indicator, the second test-level comprehension indicator is generated based upon test level rather than question level factors. After the first and second test-level comprehension indicators are generated, they may be used to derive an overall comprehension indicator for the individual for that test.

Abstract: Method(s), stored instruction(s), and computing device(s) are provided for automatically generating different subsets of questions and/or automatically assigning the different subsets of questions to different test participants. The computing device(s) store information that includes test questions, test version generation criteria, and test version assignment criteria. The computing device(s) automatically determine, using the test version generation criteria, subsets of test questions that differ from each other by at least one question. The computing device(s) automatically assign, using the test version assignment criteria, subsets of test questions, which differ from each other by at least one question, to different test participants. The computing device(s) then cause administration of at least one of the different versions to at least one of the different test participants.

Abstract: A method and system are provided for enabling one or more attribute values of a learning object to be derived and updated based upon learner actions taken by a plurality of learners on that learning object or on one or more related learning objects. To keep the attribute values current, the attribute values may be updated as new/additional information is received. Once the one or more attribute values are derived and updated, they can be used to make intelligent and effective decisions on whether and when to use the learning object to educate a learner.
