AIインシデントの軌跡を実用的に分類する

Public AI incident database counts conflate changes in reporting propensity, deployment growth, and shifts in harm frequency per unit of exposure. These issues introduce significant uncertainties challenging public and corporate policy frameworks centred on realized risks. We propose a simple framework that establishes clear points of inquiry, separately estimates exposure from harm-rate trends, and then classifies into meaningful trajectory categories for governance decisions. The framework combines a structured monitoring question format (SORT) to clarify coverage decisions, a tiered estimation procedure calibrated to available evidence, and LLM-assisted incident matching against public databases. Applied to various monitoring questions, we draw conclusions regarding the monitoring ecosystem more broadly: Providing an essential interpretative classification, determining what can and cannot be claimed, and establishing that exposure estimation is required as AI deployments become increasingly common.
