Researchers have developed the Probabilistic Allen Algebra (PAA), an extension of Allen's interval algebra designed to handle temporal uncertainty. PAA models time points using Gaussian distributions and intervals with Gaussian midpoints and truncated-Gaussian durations. This framework allows for graded temporal relations like "roughly during" by deriving probabilities from distributions over interval boundaries, rather than assigning crisp scores. The system is validated through Monte Carlo simulations and is available as an open-source Python package. AI
