Simple Trust Network Demo
|Back to Homepage|
Left-click and drag opinion points and base rates to set the argument opinions. The demo shows how this simple trust network can be analysed using subjective logic operators to derive A's opinion about X, as shown by the bottom opinion triangle. In detail, trust transitivity means that analyst A discounts B's advice opinion about X by A's own trust opinion about B, and the same for C. Finally, A fuses the two discounted advice opinions using the cumulative fusion operator, producing the bottom derived opinion about X. See the book on subjective logic for the mathematical details.
