DCI experiment corpora
This private dataset repository stores the corpora used by the archived DCI experiments, together with the scripts needed to reconstruct nested scaling variants and regenerate omitted indices.
The repository preserves the original corpora/... paths.
Contents
| Path | Stored size | Files | Contents |
|---|---|---|---|
corpora/bcp_fineweb_nested_10m/ |
10.61 GiB | 104 | Canonical ordered 10M BrowseComp-Plus + FineWeb corpus. It contains 101 Zstandard-compressed JSONL shards, the source/composition manifest, per-shard line counts, and the build log. |
corpora/wiki18/ |
4.77 GiB | 3 | Canonical wiki-18.jsonl.gz, the recorded assembly sizes, and the download log. The trajectory repository contains only the requested 50-question subsets, while this is the shared retrieval corpus. |
corpora/public_ir/ |
0.55 GiB | 42 | Pinned BRIGHT Parquet snapshots and BEIR Arguana/SciFact corpora, queries, qrels, and source README files used by the relevance-ranking experiments. |
scripts/trim_nested_scaling_corpus.py |
4 KiB | 1 | Streams the ordered 10M corpus and reconstructs the smaller nested corpus variants without requiring separately stored copies. |
scripts/rebuild_indices.md |
2 KiB | 1 | Recorded commands and model settings for rebuilding Pyserini/Lucene, dense, and Wiki18 E5 indices. |
Nested BCP + FineWeb corpus
The canonical collection contains 10,000,195 documents in this order:
- 100,195 BrowseComp-Plus documents.
- 9,900,000 documents from
HuggingFaceFW/fineweb,sample-10BT, splittrain.
The stored source manifest records seed 42 and a logical shard size of 100,000. The observed nested experiment boundaries are:
| Variant | Documents |
|---|---|
| 100K | 100,195 |
| 200K | 200,197 |
| 400K | 400,195 |
| 800K | 800,195 |
| 10M | 10,000,195 |
Reconstruct a smaller variant:
python scripts/trim_nested_scaling_corpus.py \
--source corpora/bcp_fineweb_nested_10m/collection \
--size 800k \
--output /path/to/bcp800k
The collection shards use Zstandard level 15 with long-window mode. A long-window decoder may be required:
zstd -d --long=31 \
corpora/bcp_fineweb_nested_10m/collection/docs_00000.jsonl.zst
Index policy
Generated FAISS, dense, Lucene, and Pyserini indices are intentionally not
stored. They can be regenerated from the canonical corpora using
scripts/rebuild_indices.md.
Integrity
file_manifest.tsv records type, size, mtime, SHA-256, relative path, and
symlink target for every corpus and included script. SHA256SUMS provides a
standard checksum list:
sha256sum -c SHA256SUMS
The repository is private because the combined corpus contains material from multiple upstream datasets with distinct licensing and redistribution terms.
