A system for performing FRIAR Code-based adjudication includes a FRIAR Code processor configured to match an extracted FRIAR identified element against a Knowledge Base set of reference FRIAR identified elements, a FRIAR Transaction Originator Code processor, a FRIAR Account Code processor, a FRIAR Code selection processor for defining a rule set to be applied to the extracted FRIAR identified element and the large indefinite quantity of reference FRIAR identified elements and configured to generate a total FRIAR Code identification function, a FRIAR Code threshold processor configured to generate a context-dependent threshold for an acceptable code decision, and a decision processor configured to compare the total FRIAR Code functions to the context-dependent threshold and determine whether to accumulate and aggregate further FRIAR Code aggregation, provide system alerts, render an automatic reclassification, or to generate an auto-accept/auto-deny decision-result.
