Abstract
Letter of Credit (L/C) is a trade finance product that is popularly used worldwide. L/C is a conditional guarantee of payment from issuing bank to the seller. The condition that has to be met is presentation of documents which complies with the L/C and every applicable rule such as UCP 600. Invoice is one of the most common documents that mostly required in L/C conditions. In current practices, compliance of the invoices is examined manually. These practices affect the accuracy, cost, and time efficiency of the examination considering the high L/C transaction volume. The needs to automate this examination process appear due to this background. This research proposed a tools pipeline that automate the invoice examination process. Three main processes proposed are; Text data extraction from L/C, Data extraction from invoice, and rule-based matching between pre-extracted data. Several techniques are used for the proposed processes namely, rule-based named entity for text data extraction from L/C, connected component analysis for determination of signature location, Hough transform for de-skewing the image, and Gaussian blur for minimization noise. Tesseract OCR 5.0 is used for OCR engines. To test the effectiveness of proposed method, experiment is done in 3 processes. First, text data extraction from L/C. Dataset used in this step are 47 L/Cs in text format. Second, data extraction from invoice images. Dataset used in this step are 16 invoices with 13 different formats. Third, rule-based matching between previously extracted data. Dataset used in this step are extracted data from previous step. Experiments results are 100% accuracy for text data extraction from L/C using gazetteers, average of 90.62% accuracy for data extraction from invoice images and average of 83.75% accuracy for rule-based matching between preextracted data.
