| # soc91-labels |
|
|
| Mirror of the R2 prefix `soc91-labels/` from `soc127-dedup` (Cloudflare R2) into a private |
| HF Dataset. Generated by `scripts/handoff/mirror_r2_sidecar_prefix.py` on |
| 2026-05-23. |
|
|
| Each row in the source R2 parquets is preserved, with one additional column appended: |
| `source_shard_path` — the R2 object key the row came from. This lets you reconstruct |
| the per-shard view if needed. |
|
|
| ## Counts |
|
|
| | | Source (R2) | Mirror (this dataset) | |
| |---|---|---| |
| | Files | 58,465 | 2,719 (concat into ~60 MB chunks) | |
| | Size | ~150 GB (approx, mixed schemas) | 169.94 GB | |
|
|
| ## Loading |
|
|
| ```python |
| from datasets import load_dataset |
| ds = load_dataset("HCAI-Lab/soc91-labels") |
| # or for a single chunk: |
| import pyarrow.parquet as pq |
| table = pq.read_table("data_00000.parquet") |
| ``` |
|
|
| ## Schema |
|
|
| Schema matches the per-shard WebOrganizer sidecar parquet schema as defined in |
| `src/dolma/sidecar_manifest_fields.py:43-124` (data-attribution repo), plus the appended |
| `source_shard_path` column. The underlying classifier produced both an "old" schema |
| (label ids only) and a "new" schema (label ids plus per-label probability vectors); |
| the concatenated table promotes nullable columns so rows from both schemas coexist. |
|
|
| Per-row fields (subset; see source for the full list): |
|
|
| - `doc_id` — Dolma document UUID |
| - `weborganizer_topic_id`, `weborganizer_topic` — top-1 topic class (24 categories) |
| - `weborganizer_format_id`, `weborganizer_format` — top-1 format class (24 categories) |
| - `weborganizer_topic_confidence`, `weborganizer_format_confidence` — top-1 probabilities |
| - `weborganizer_topic_probabilities`, `weborganizer_format_probabilities` — full probability vectors (new-schema rows only; null on old-schema rows) |
| - `source_shard_path` — the R2 object key the row originated from |
|
|
| ## Lineage |
|
|
| - SOC-91 (initial label generation) |
| - SOC-142 (inverted-quality-label fix at commit `3342baf`; affects the quality sidecars in |
| `HCAI-Lab/soc139-quality-sidecars`, not the topic/format labels here) |
|
|
| ## Notes |
|
|
| - The chunked-write/stream-upload pipeline succeeded and committed all 2,719 chunks. |
| - The original `write_readme()` step crashed (after upload) because the staging directory |
| files were already deleted by the stream-upload pattern. This README was written by |
| hand after the fact based on the script's final log output (`wrote 2719 chunks total`). |
