# Placeholder Labs Academic Pool

Public organic academic pretraining pool with 41,112,360 documents and
456,510,356,112 Dolma-2 tokens.

- Common Pile peS2o Filtered multidisciplinary research papers
- Dolma 3 olmOCR Science PDFs (score >=0.30, academic evidence, clean extraction)
- Common Pile LibreTexts Filtered open textbook sections
- `quality_bin` is null; source scores are retained only as source-specific evidence
- labels: document type and publication year
- exact dedup plus verified cross-source near dedup; MinHash alone never deletes
- inline citations and bibliographies are preserved

## Actual source totals

- `allenai/dolma3_pool`: 35,205,487 documents, 418,156,445,614 Dolma-2 tokens
- `common-pile/libretexts_filtered`: 38,513 documents, 80,583,538 Dolma-2 tokens
- `common-pile/peS2o_filtered`: 5,868,360 documents, 38,273,326,960 Dolma-2 tokens

The selected survivors represent 294,486 additional
exact or verified-near duplicate rows that were removed. Licence row counts and the
immutable ID-set digest are recorded in `RELEASE.json`.

The `odc-by-1.0` value on olmOCR rows describes the upstream Dolma dataset licence;
it is not a blanket claim that every underlying PDF is openly copyrighted. peS2o and
LibreTexts retain their available per-document licence evidence.

See `RELEASE.json` for the immutable file and ID-set manifest.

## Evaluation decontamination

The final corpus was screened after cross-source deduplication. Complete documents were excluded on a policy match; the `decontamination` configuration contains the auditable exclusion ledger without raw evaluation prompts.
