VerifiedTraditional OCR technology excels at converting image text into machine-readable text, but has limited ability to understand the semantic structure of documents.68% similarUnverifiedGeneral-purpose large models tend to be strong on plain text and tables, but weaker than dedicated OCR pipelines on layout and chart tasks.67% similarUnverifiedModern chunkers typically read the plain-text layer output by OCR directly and discard coordinate information, causing cells in two adjacent columns of a table to possibly be concatenated into a meaningless string in the OCR plain-text output, which the chunker then treats as a semantically complete paragraph and sends off for embedding.66% similarUnverifiedOpen the page with pdfplumber and call page.extract_text(); if it returns an empty string or large numbers of (cid:NN), the text layer is missing or font mapping is abnormal, and you should switch to an OCR/ML pipeline.65% similar
