Uncertainty quantification

Uncertainty quantification refers to methods for estimating and communicating how reliable or uncertain a model's predictions are. In misinformation detection, quantifying uncertainty enables systems to:

  • Defer to human review when confidence is low
  • Provide calibrated confidence estimates to downstream decision-makers
  • Improve decisions in high-stakes settings where knowing the uncertainty is as important as the point estimate

Methods

  • Confidence intervals: Construct intervals that contain the true value with probability \((1-\alpha)\)
  • Calibration: Ensure predicted confidence matches actual accuracy
  • Bayesian approaches: Model uncertainty via posterior distributions
  • Ensemble methods: Combine multiple models to estimate disagreement/uncertainty

In fact-checking

Model predictions in fact-checking need uncertainty estimates to support human-in-the-loop workflows. Amatya et al. (2026) uses prediction intervals to quantify uncertainty in claim check-worthiness detection.
