Dynamically Generating Policy Compliant Dialogues for Physical Access Control

We develop an Interactive Voice Response (IVR) system that has a verbal dialog with potential entrants to secured buildings to permit legitimate people. Our system dynamically generates these dialogs from physical access control policies. Contents, number nor the sequence of questions are pre-programmed, but dynamically generated based on the policy and the provided answers. We use Item Response Theory (IRT) to generate a non-repeating, yet a minimal sequence of questions so that all permitted entrants would satisfy an acceptable level of competence and accuracy estimation that protects against the exposure of questions generated from policies with large number of rules.
