Here’s a short, practical post/guide on combining (a common machine translation metric) with PDF workflows for evaluation or reporting. bleu+pdf+work

Summarizing long PDF reports (e.g., legal filings, scientific papers). BLEU can measure how closely the summary aligns with a human-created abstract. It is critical to acknowledge that BLEU is

It is critical to acknowledge that BLEU is not a silver bullet for document quality. A perfect lexical match (BLEU=1.0) might still result in a document that is structurally useless. As noted in critiques of traditional metrics, a document parser could achieve a high BLEU score by extracting text verbatim from a PDF's internal text layer while completely ignoring the document's layout, merging tables into plain text, and destroying all structural logic. Consequently, while BLEU excels at measuring (accuracy of the words used), it struggles with recall (capturing all necessary information) and completely ignores layout , which is often a critical dimension of meaning in structured documents like forms or financial statements. Consequently, while BLEU excels at measuring (accuracy of
