We present a machine-learned model that can automatically detect when a student using an intelligent tutoring system is off-task, i.e., engaged in behavior which does not involve ...
Model checkers were originally developed to support the formal verification of high-level design models of distributed system designs. Over the years, they have become unmatched in...
Abstract. Internet users are becoming increasingly concerned about their personal information being collected and used by Web service providers. They want to ensure that it is stor...
In this paper, we introduce a new, formal model of learning object metadata. The model enables more formal, rigorous reasoning over metadata. An important feature of the model is t...
Probabilistic models have recently been utilized for the optimization of large combinatorial search problems. However, complex probabilistic models that attempt to capture interpa...
