Claim 16:
17. The system according to claim 11, wherein the server is further configured to:
obtain training call data for a plurality training calls and a plurality of training labels corresponding to the training call data of the plurality of training calls;
obtain the probability value indicating a probability of occurrence of a training carrier metadata value of the type of carrier metadata value correlated to a training derived metadata value of the type of derived metadata value for the plurality of training calls;
for each training call, generate a training feature vector for the training call based upon the probability value, the training derived metadata value, and the training carrier metadata value; and
train the machine-learning architecture to determine the risk score by applying the machine-learning architecture on each training feature vector of each training call and each training label corresponding to the training call.
