Post processing and language technology in OCR


Jesse De Does from INL follows Katrien by introducing a post-processing Text and Error Profiling tool that looks similar to the IBM tool demonstrated by Niall earlier. This tool differs through the use of ‘text profiling’, whereby language and text is analysed on the basis of frequency and logic. It also allows for batch correction … Continue reading "Post processing and language technology in OCR"
