The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI- TT) project is to create the Contextual Linkaging for Undergraduate Education (CLUE) Service that analyzes transcriptions from class recordings and automatically identifies related resources in a student’s learning ecosystem. This system will allow students to search class videos to find when a concept was discussed, indicate moments during a class when they are confused, and subsequently receive additional information on the confusing topics. By automatically identifying when key concepts were discussed during class, this project will enable educational platforms to deliver content to the learner personalized to the material presented during each class session. Instructors will receive feedback on which resources students find valuable for each topic. The CLUE Service will be designed to help educational resource providers by providing contextual linkages to resources in other educational platforms. University Chief Information Officers will find value as a way to contextually integrate the numerous learning resources they support.The proposed project builds on former NSF-funded projects and requires technical expertise in natural language processing and design of educational technologies. The CLUE Service will use computer-generated transcriptions from class captures to identify key terms and phrases discussed during class sessions. The combination of analyzed key terms and corresponding timestamps will allow contextual linkages to be created between moments in class captures and other educational resources. The envisioned prototype will be a subscribable Application Programming Interface (API) that will allow contextual linkages between educational services. Technical challenges for this project include how to best design unsupervised machine learning to either identify keywords and/or topics in a class session along with the best timestamp(s) in class to represent those keywords or topics and how to provide a resource that can be used with any video delivery system so the student can make known when they would like additional information during a streaming or recorded class session. Initially, the results of this research will be made available to participating instructors or their assistants with tools that will allow them to assess the potential value of the recommended resources to their students. This feedback will inform improvements in resource selection for the CLUE service.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该创新技术翻译合作伙伴关系（PFI-TT）项目的更广泛的影响/商业潜力是创建本科教育上下文链接（CLUE）服务，该服务分析来自课堂录音的翻译，并自动识别学生学习生态系统中的相关资源。该系统将允许学生搜索课堂视频，以查找讨论概念的时间，指示课堂上他们感到困惑的时刻，并随后接收有关令人困惑的主题的其他信息。通过自动识别在课堂上讨论的关键概念，该项目将使教育平台能够向学习者提供个性化的内容，以适应每个课堂上呈现的材料。教师将收到反馈，了解学生认为哪些资源对每个主题有价值。CLUE服务旨在通过提供与其他教育平台资源的上下文链接来帮助教育资源提供者。大学首席信息官将发现作为一种方式的上下文集成他们支持的众多学习资源的价值。拟议的项目建立在前NSF资助的项目，并需要在自然语言处理和教育技术设计的技术专长。CLUE服务将使用计算机生成的课堂截图来识别课堂上讨论的关键术语和短语。分析的关键术语和相应的时间戳的组合将允许在课堂捕捉和其他教育资源的时刻之间创建上下文链接。设想的原型将是一个可订阅的应用程序编程接口（API），将允许教育服务之间的上下文链接。该项目的技术挑战包括如何最好地设计无监督机器学习，以识别课堂会话中的关键字和/或主题沿着课堂中代表这些关键字或主题的最佳时间戳，以及如何提供可与任何视频传输系统一起使用的资源，以便学生可以在流式传输或录制的课堂会话期间了解他们想要的其他信息。最初，这项研究的结果将提供给参与的教师或他们的助手，使他们能够评估推荐的资源对学生的潜在价值。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
