Beyond States: Investigating the Effects of Context on User Modeling with Feature-Conditioned Markov Models

Jana Isabelle Friese, Andreas Konstantin Kruff, Timo Breuer +2

User behavior simulation is widely used to evaluate interactive information retrieval systems, but classical state-based approaches (e.g., Markov models) have limited ability to in…

Validating Synthetic Usage Data in Living Lab Environments

Timo Breuer, Norbert Fuhr, Philipp Schaer

Evaluating retrieval performance without editorial relevance judgments is challenging, but instead, user interactions can be used as relevance signals. Living labs offer a way for…
