govdocs1: source PDF files
[!NOTE]
Converted versions of other document types (word, txt, etc) are available in this repo
This is ~220,000 open-access PDF documents (about 6.6M pages) from the dataset govdocs1. It wants to be OCR'd.
Uploaded as tar file pieces of ~10 GiB each due to size/file count limits with an index.csv covering details
5,000 randomly sampled PDFs are available unarchived in sample/. Hugging Face supports previewing these in-browser, for example this one… See the full description on the dataset page: https://huggingface.co/datasets/BEE-spoke-data/govdocs1-pdf-source.eiken-pdfunboxgov-khmdhs-pdfs
KHMDHS Contract Attachment PDFs
Per-contract attachment PDFs from the Greek public-procurement registry
KHMDHS, downsampled with Ghostscript /ebook (~150 DPI) for fast viewing
and compact storage. Files are packed into per-month SQLite shards
(pdfs/<YYYY-MM>.sqlite, one row per ΑΔΑΜ, keyed by referenceNumber).
These are lossy, downsampled copies. The authoritative originals remain at
KHMDHS: https://cerpp.eprocurement.gov.gr/khmdhs-opendata/contract/attachment/{ΑΔΑΜ}.

Evaluation_of_OpenSource_Models_for_PDF_Injection_Recognition
Injected PDFs - Model Evaluation
This repository holds the model evaluation stage of a project on detecting harmless-but-real
attack payloads injected into PDF files, together with the artefacts it produced for the
application.
Nothing is trained here. Seven off-the-shelf models are measured against the same 1,100 PDFs,
and the two winners are exported for the app to load.

StenCore — FinePDFs-Edu Curated
By StentorLabs
StenCore is StentorLabs' first dataset release — a quality-first resource built from the ground up for training language models. Derived from HuggingFaceFW/finepdfs-edu, every document passed a 14-stage automated curation pipeline including heuristic filtering, language ID, PII redaction, toxicity screening, eval decontamination, multi-strategy deduplication, KenLM + neural perplexity scoring, and domain reweighting.

plus a separate downloadable demonstration made from original synthetic PDFs.
"Clean" means the original document before our embedding, not malware-free.

IMSLP PDF Index
This dataset is the canonical PDF-level index for the ReScore IMSLP PDF
collection. It contains one row per unique IMSLP PDF and points to the PDF
payload stored in cminst/imslp-raw-pdf-collection.
The PDF payload repository is append-only and may contain duplicate rows from
retry launches. This index is deduplicated by imslp_id; duplicate content was
validated to have identical SHA256, byte size, and page count before publishing.

Healthcare.pdf — representative release (v1.0)
A PDF-grounding benchmark for healthcare document work: 25 expert-authored tasks grounded in
25 real healthcare documents, covering 7 occupations across clinical and pharmacy practice.
Each task puts a practitioner in a realistic situation, gives them a real document, and asks a sequence of
sub-questions that must be answered from that document. Answers are graded against a four-tier rubric.

这是一个格式演示，不是训练语料。 25 页、18 份文档，只够说明 schema 长什么样、
三种视图怎么取。真实语料是 21.8 万份 PDF 的量级。
