This article explores why this combination matters, how to implement it, and best practices for making BLEU scores meaningful when working with PDF documents. What is BLEU Score? Developed by IBM in 2002, BLEU is an algorithm for evaluating the quality of machine-translated text against one or more human reference translations. It works by analyzing n-gram overlap (sequences of n words) between the candidate translation (machine output) and the reference (human gold standard).

By following the pipeline described—high-fidelity extraction, sentence alignment, automated BLEU computation, and workflow integration—you can turn BLEU from an academic curiosity into a practical driver of translation quality. It works by analyzing n-gram overlap (sequences of
