Abstract: An authorization machine may be used by an authorizing entity to aggregate and analyze multiple reports that are pertinent to a performer of entertainment. The authorization machine may determine the performer's potential earnings for performing at an event to occur in the future. This determination may be based on one or more revenue-related reports that describe past transactions attributable at least in part to the performer. The authorization machine may then determine a likelihood that the performer will actually attain the potential earnings by performing at the event. This likelihood may be determined as a risk score based on one or more sentiment-related reports that describe the performer's popularity. Based on the potential earnings and the likelihood of attaining them, the authorization machine may authorize an advance payment corresponding to the performer.
