SMEs & BEKEE Session Manager

Context

Knowledge elicitation in BayesiaLab allows a group of Subject Matter Experts (SMEs) to define or refine a network’s Conditional Probability Tables by providing Assessments. The SMEs & BEKEE Session Manager is where you declare these experts and run the BEKEE (Bayesia Expert Knowledge Elicitation Environment) sessions through which they provide their input.

Each SME is described by an e-mail address, a first and last name, a Credibility (the weight given to their contribution when individual assessments are combined into a consensus), an image, a color, and an optional comment.
