Abstract : However, some firms still opt to handle email purchase orders manually, leading to inefficiency, mistakes, and unwanted delays. In this regard, the emails are not only written in simple text form but are also scanned and/or provided as PDF files, thereby complicating the process of extracting data from such emails. This research suggests the use of a completely automated process that will manage the emails in order to structure the extracted data for use by the ERP system. For this reason, a confidence-aware hybrid approach was applied to extract data about the products, quantity, and even shipping details from the purchase orders based on the language model, named entities, and rule approaches. With the use of the confidence-aware approach, the system identifies reliable data, while the input quality controller handles text misrecognition and differences in email format. The whole process involves retrieving emails, doing OCR, validating the data, and importing into the ERP system.

Keywords : Purchase Order Automation, Optical Character Recognition (OCR), Named Entity Recognition (NER), ERP Integration.
