Abstract: A system 80 for personalized e-leaming includes a Hierarchical Knowledge Tracing (HKT) model unit 81 which includes two sequential models comprising of a lower level model and a higher level model, wherein the lower level model estimates and updates the estimate of knowledge state of a learner from a question-response data of the learner while the learner is active (in-session) on the e-leaming application and predicts the probability of answering a question within the domain using the estimate of knowledge state, and the higher level model updates the knowledge state estimate of the lower level model when a new session starts.

Abstract: An object is to provide an information processing apparatus capable of analyzing operation log data that can be acquired through a digital device and effectively using the operation log data. An information processing apparatus (10) according to the present disclosure includes an information collection unit (11) configured to collect an operation log generated when a digital device is operated from a plurality of the digital devices, an execution unit (12) configured to co-cluster operator information and content information. The operator information is for identifying an operator of the digital device included in a plurality of the operation logs, and the content information is about content viewed by the operator using the digital device, and a post-processing unit (13) configured to create confirmation data using an execution result of the co-clustering.
