About this paper

Nolwenn Bernard

This research outlines a plan to enhance user simulation for Conversational Information Access (CIA) agents, aiming to improve both training and evaluation processes by addressing the limitations of single-goal simulators and the need for robust assessment of simulator realism. It proposes developing hybrid and multi-goal user simulators to better reflect complex, real-world user interactions.

Key insights

  • User simulators require different characteristics depending on whether they are used for training or evaluating CIA agents, with interpretability being more critical for evaluation and content for training.
  • A hybrid approach combining various simulator types can leverage individual strengths (e.g., interpretability from agenda-based, flexibility from LLM-based) to create more versatile and powerful tools.
  • Extending user simulation to multi-goal scenarios is crucial for developing CIA agents capable of handling the dynamic and complex information-seeking behaviors of real users.
