In practice, agents are budget-limited, and investments in acquiring witness (or reputation) information will affect the budget that can be used for direct interaction.

Abstract

Utilizing witness information to supplement direct evidence is commonly used to build assessments of the trustworthiness of agents.

The process of acquiring this kind of evidence is, however, typically assumed to be cost-free. In practice, agents are budget-limited, and investments in acquiring witness (or reputation) information will affect the budget that can be used for direct interaction. At the same time, acquiring such witness information can help in making better trust decisions.

We explore this trade-off, formalising it as a budget-limited multi-armed
bandit problem, and evaluate the effectiveness of algorithms to guide this
decision process
