1. A computer-implemented method for classifying freight-truck-transaction documents at a freight-truck-transaction document classification device, the method comprising: receiving freight-truck-transaction document data corresponding to documents related to the transport of freight by truck, at the freight-truck-transaction document classification device, wherein the document data comprises freight-truck-transaction document text data; detecting, at the freight-truck-transaction document classification device, an existence of, or an absence of, one or more predetermined freight-truck-transaction document text fields in the documents based upon, at least in part, the document data, wherein the predetermined freight-truck-transaction document text fields include one or more of: bill of lading, invoice, ticket number, log, sale, gallons, unloading, receipt, turnpike, toll, and confirmation; assigning, at the freight-truck-transaction document classification device, a value to the one or more predetermined freight-truck-transaction document text fields based upon, at least in part, the existence of, or the absence of, the one or more predetermined freight-truck-transaction document text fields in the documents; determining, at the freight-truck-transaction document classification device, a score for each of the documents based upon, at least in part, values assigned to the one or more predetermined freight-truck-transaction document text fields; determining, at the freight-truck-transaction document classification device, whether each document is classifiable based upon, at least in part, the score for each document; and in response to determining whether one or more of the documents are classifiable, classifying the one or more documents as a document type based upon, at least in part, the score, and predefined document classification rules, wherein the document type is at least one of a bill of lading, a proofs of delivery, a packing list, a receipt, a fuel and mileage document, an accident report, a customs form, an inspections forms, and a toll document.
