Abstract: Methods and systems are provided for personalizing foreign language instruction. In particular, the systems and methods provided apply artificial intelligence to novel tasks related to teaching foreign languages such as detecting skill levels of users, generating personalized course curriculums for individual users based on the learning goals and initial skill level of a user, generating custom assignment assets for those goals based on current strengths, weakness, generating content for custom questions for those assignment assets, and dynamically tracking and updating the skill level of the user during the course.

Abstract: Methods and systems are provided for analyzing content items from digital content sources with respect to activity on communication networks. Content items are retrieved based on tracking set definitions from digital content sources via a network, and metadata is extracted from the retrieved content items. Communication related to the content items on one or more communication networks is periodically monitored, and the monitored communication is used to generate content scores for the retrieved content items based on one or more static content scores, dynamic content scores, and contextual relevance scores. The periodic monitoring allows trending information with respect to content items, authors, topics, and/or other data elements to be surfaced and analyzed.

Abstract: A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing network resources are provided. A quarantine coordination client (QCC) located on a client machine acquires statements of health from a plurality of quarantine policy clients. The QCC packages the statements and provides the package to a quarantine enforcement client (QEC). The QEC sends the package to a quarantine enforcement server (QES) with a request for network access. The QES passes the package to a quarantine coordination server (QCS) that disassembles the package and passes the individual statements of health to corresponding quarantine policy servers (QPS). The QPSs validate the statements of health and inform the QCS of the result. If the client provided valid statements of health, the QES grants the client access to the network.
