| # 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. |
|
|
| - Removed documents: **5,047** |
| - Removed Dolma-2 tokens: **422,922,699** |
