High-accuracy Decision of Call-triage by Using Bayesian Network

Abstract

A new call-triage system, a key part of emergency support system with stochastic network model is examined. The call-triage is an operation allowing the efficient decision of service grade and dispatching of suitable rescue team service from phone call information. Nowadays, the call-triage is being trialed on a few cities and is achieving an effect. However, there is the issue that if under-triage in which the condition of sick person is estimated more lightly is eliminated, the efficiency is degraded (over-triage). In this report, in order to overcome the issue, the Bayesian network scheme is examined to the call-triage system. The experiments with real call-triage data set results show the Bayesian network achieves precision enhancement.
