pretty_name: Red Pajama V2 Data Foundation
---

### Getting Started

The full RedPajama-V2 dataset is a data foundation that includes a over 100B text documents coming from 84 CommonCrawl
snapshots and processed using the [CCNet](https://github.com/facebookresearch/cc_net) pipeline. Out of these, there are
30B documents in the corpus that additionally come with quality signals.

Check out our [blog post](XXXXX) for more details on the build process, dataset structure and schema.

To familiarize yourself with the dataset, you can load the sample dataset with the following command:

```python
from datasets import load_dataset

ds = load_dataset("togethercomputer/RedPajama-Data-V2", name="sample") 
```

Alternatively, you can also directly download the files using the following instructions, using english data from the
`2023-06` snapshot and the `head_middle` partition as an example. The full set of CC snapshots included in the dataset
is given in `_CC_SNAPSHOT_IDS`, and the available partitions are `tail`, `head_middle`. The available language tags are
`en`, `de`, `fr`, `es`, `it`.

```bash
CC_SNAPSHOT="2023-06"
LANG="en"
PARTITION="head_middle"
BASE_URL="https://data.together.xyz/redpajama-data-v2/v1.0.0/"

listings_file="${LANG}-${CC_SNAPSHOT}-${PARTITION}.txt"
wget "${BASE_URL}/listings/${listings_file}"

# download documents
while read line; do
  url="${BASE_URL}/documents/${line}.json.gz"
  dest="documents/${line}.json.gz"
  mkdir -p $(dirname $dest)
  wget "$line" -O "$dest"
done <"${LANG}-${CC_SNAPSHOT}-${PARTITION}.txt"

# download other components
COMPS=("quality_signals" "minhash" "duplicates")
for comp in "${COMPS[@]}"; do
  while read line; do
    url="${BASE_URL}/${comp}/${line}.${comp}.json.gz"
    dest="${comp}/${line}.${comp}.json.gz"
    mkdir -p $(dirname $dest)
    wget "$line" -O "$dest"
  done <"${LANG}-${CC_SNAPSHOT}-${PARTITION}.txt"
done

```

A full set of scripts to recreate the dataset including the quality signals can be
found [here](https://github.com/togethercomputer/RedPajama-Data).

### Dataset Summary

RedPajama-V2 is a data foundation for which includes over 100B text documents, out of which 30B documents come with
quality annotations.

### Languages

English, German, French, Italian, Spanish

## Dataset Structure

The datset is structure into four components, each following the same key structure:

```
├── documents
    ├── 2018-43
        ├── 0000
            ├── en_head.json.gz
            ├── ...
            ├── it_middle.json.gz
├── quality_signals
    ├── 2018-43
        ├── 0000
            ├── en_head.signals.json.gz
            ├── ...
            ├── it_middle.json.gz
├── duplicates
    ├── 2018-43
        ├── 0000
            ├── en_head.duplicates.parquet
            ├── ...
            ├── it_middle.duplicates.parquet
├── minhash
    ├── 2018-43
        ├── 0000
            ├── en_head.minhash.parquet
            ├── ...
            ├── it_middle.minhash.parquet
```

Documents files, which contain the text, folow the schema defined by CCNet, and the quality signals follow the schema

```json
{
  "id": "2018-43/0000/en_head.json.gz/0",
  "id_int": 7972430436813205988,
  "metadata": {
    "cc_segment": "crawl-data/...",
    "cc_net_source": "2018-43/0000/en_head.json.gz",
    "url": "...",
    "source_domain": "...",
    "language": "en",
    "snapshot_id": "2018-43"
  },
  "quality_signals": {
    "ccnet_original_length": [
      [
        0,
        7033,
        8711.0
      ]
    ],
    ...,
    "rps_doc_stop_word_fraction": [
      [
        0,
        7033,
        0.45121107
      ]
    ],
    "rps_lines_num_words": [
      [
        0,
        25,
        2
      ],
      ...,
      [
        6980,
        7033,
        10
      ]
    ]
  }
}
```

where signal scores are encoded as list of tuple `(start, end, score)`, where `start` and `end` are the locations in the
`raw_content` string where the `score` applies.

## Dataset Creation

The dataset is based on 84 snapshots provided by CommonCrawl.
