We present a personalised retrieval system that captures explicit relevance feedback to build an evolving user profile with multiple aspects. The user profile is used to proactively retrieve results between search sessions to support multi-session search tasks. This approach to supporting users with their multi-session search tasks is evaluated in ...

Massive open online courses (MOOCs) provide learning materials and automated assessments for large numbers of virtual users. Because every interaction is recorded, we can longitudinally model performance over the course of the class. We create a panel model of achievement in an early MOOC to estimate within- and between-user differences. ...
