A web-based tool for expert elicitation in distributed teams

Abstract

We present in this paper a web-based tool developed to enable expert elicitation of the probabilities associated with a Bayesian Network. The motivation behind this tool is to enable assessment of probabilities from a distributed team of experts when face-to-face elicitation is not an option, for instance because of time and budget constraints. In addition to the ability to customize surveys, the tool provides support for both quantitative and qualitative elicitation, and offers administrative features such as elicitation surveys management and probability aggregation.
