MidTool-fasttext-pdf-quality-classifier
The fastText quality classifier used to filter PDF documents when building MidTool-Mix. It scores a document on whether it is useful tool-use / developer-facing technical material (manuals, product handbooks, platform documentation) rather than generic or noisy PDF-extraction output.
It is the PDF counterpart of MidTool-fasttext-web-quality-classifier, trained the same way but applied with a stricter threshold, since PDF extraction is noisier than web text.
