Eliciting Bayesian Network Structures with the BaSE Protocol: A Practical Demonstration

Ross Pearson, Monash University
Tuesday, 10th February 2026

This 30 minute practical session introduces a software platform implementing the BaSE (Bayesian Network Structure Elicitation) protocol,  designed to facilitate the elicitation of Bayesian Network structures from groups of experts. Webinar participants will learn how to run a structured elicitation session leveraging the software, which is freely accessible online, with access granted upon request. While ideal for groups of three or more, the tool can also be adapted for individual use.

The tool guides users through three rounds of elicitation:

●        Variable elicitation – identifying key variables

●        Structure elicitation – defining the relationships between variables

●        Face validation – reviewing the aggregated structure with expert input.
