Lucie Training Dataset Card

The Lucie Training Dataset is a curated collection of text data in English, French, German, Spanish and Italian culled from a variety of sources including: web data, video subtitles, academic papers, digital books, newspapers, and magazines, some of which were processed by Optical Character Recognition (OCR). It also contains samples of diverse programming languages.

The Lucie Training Dataset was used to pretrain Lucie-7B, a foundation LLM with strong capabilities in French and English. Code for data preparation can be found in the training respository for Lucie-7B. Due to the licenses of a few subcorpora, the Lucie Training Dataset is released under a CC BY-NC-SA 4.0. A subset available for commercial use will be released soon.

Table of Contents:

Dataset Description

This dataset is intended to provide extensive and diverse multilingual data for training Large Language Models (LLMs). Here are some of the principal features of the corpus:

  • Data mix:
    • The dataset contains more French than English data -- it is in fact one of the biggest collections of French text data that has been preprocessed for LLM training -- with the aim of minimizing anglo-centric cultural biases.
    • German, Spanish and Italian are also represented in small amounts.
    • Code is included to boost the reasoning capabilities of LLMs.
  • Data filtering and deduplication:
    • The dataset has been cleaned in an effort to remove very low-quality data.
    • Duplicate data samples have been removed to some extent, following best practices.
    • Web data has been filtered to minimize potentially toxic content and personally identifying information.
  • Ethics:
    • Special care has been taken to respect copyright laws and individual privacy. All newspapers, monographies, magazines and legislative documents, as well as most books, are in the public domain (which depends on the author's date of death and the country of publication). Other data are published with permissive licenses (e.g., CC BY or CC BY-SA) or, in very rare cases, CC BY-NC-SA.
    • All web data in the dataset come from sites with robots.txt files that do not forbid crawling.

Sample Metadata

In addition to the text field, which provides the content of the sample, each training sample in the corpus contains the following metadata when available:

  • language: the language of the text sample (note that this information is taken from the original data source and may be incorrect).
    Possible values:
    • the ISO 639-1 code for a given natural language ("en", "fr", "de", "es", or "it"),
    • the name of a programming language prefixed by "code:" ("code:python", "code:c++", …), or
    • a list of ISO 639-1 codes separated by commas for data containing parallel translations ("fr,en", "de,fr", "es,en", "it,en", or one of those pairs in the opposite order if the languages appear in the opposite order in the text).
  • source: an identifier for the source(s) of the text sample (Wikipedia, RedPajama, Gutenberg, …). All sources are described in detail below.
  • id: an identifier that is unique among documents from the same source.
  • url (optional): the URL of the original text sample on the web, if available.
  • title (optional): the title of the original text sample, if available.
  • author (optional): the author of the original text sample, if available.
    Note: The author name is given in plain text, except in the case of Gutenberg books, where it is the JSON serialized object of the author metadata.
  • date (optional): the publication date of the original text sample, if available.
    Note: The text format of the date depends on the source.
  • quality_signals (optional): a list of quality signals for the text sample in JSON format (which could be used for further filtering or sample weighting).
    Note: It can include indicators computed by `fasttext` and `CCNet`, statistics about occurrences of characters, words, special characters, etc.
  • extra (optional): extra information about the text sample, in JSON format. This can include metadata about the source subset, the rights, etc.

The list of metadata available for each source is provided (without the text field) in metadata_examples.json.

Dataset Composition

The following figure shows the distribution of the dataset by language (colors) and category (hatch patterns).

Dataset composition

The following table provides an overview of the dataset composition, broken down by source and language. Sources are grouped by category. The table provides the numbers of documents, words, tokens, and characters for each subset. All numbers in this table are available in the CSV file dataset_composition.csv. Token counts are computed using the tokenizer for Lucie-7B.

Configurable Subsets and Versions

As the Lucie Training Dataset is a collection of multilingual corpora from different sources, it can be divided into subsets based on the source and language of its constituent corpora.
The list of possible configurations is available in the YAML header of this README file. Each configuration corresponds to a pathname pattern in the data subdirectory.

The dataset is also available in the following versions:

  • v1.1 / main (default): The data used for the first (main) pretraining phase of Lucie-7B, which contains approximately 2.3T tokens. The statistics above apply to this version.
  • v1.2: An improved version of the main dataset, where
    • GallicaMonographies and GallicaPress have been fltered aggressively to remove documents with low OCR quality.
    • The Ubuntu_IRC and PhilPapers subsets of Pile have been refined by fixing encoding issues and removing documents in languages other than English, French, Spanish, German and Italian.
  • v1.2-recent-web : The data used for the second pretraining phase (context extension) of Lucie-7B. This version is identical to v1.2 with the exception that older snapshots of web data (before 2023 for RedPajama and before 2024 for FineWebEdu) have been excluded. All data from v1.1 that were not filtered out remain unchanged in v1.2 and v1.2-recent-web.

Except from v1.1, which is a git tag, all versions are git branches in the dataset repository (e.g. v1.2).

The Example use in Python section contains example Python code for loading and iterating over the dataset with different configurations, including source, language and version.

AmendementsParlement

  • Source: Corpus contributed by OpenLLM partners.
  • Extracted from: Regards citoyens. License: CC BY-SA.
  • Description: A collection of proposed amendments by the French parliament. Documents contain the text of the proposed amendment, the name of the associated law as well as information on who voted on the amendment and what was decided.

AmericanStories

  • Source: dell-research-harvard/AmericanStories. License: CC BY 4.0.
  • Extracted from: Chronicling America. License: Open.
  • Description: "The American Stories dataset is a collection of full article texts extracted from historical U.S. newspaper images. It includes nearly 20 million scans from the public domain Chronicling America collection maintained by the Library of Congress. The dataset is designed to address the challenges posed by complex layouts and low OCR quality in existing newspaper datasets" (from the dataset card). See the dataset composition details for statistics on documents by year. Dataset containing text retrieved through OCR.
  • Pre-processing:
    • Filtering: To filter out documents with excessive OCR errors, the dataset was refined by discarding texts with a perplexity higher than 2310, measured using a CCNET model in English (see code details). The code to compute CCNET perplexity, parallelizing on parquet files, is available here.

Claire (French and English)

  • Sources:
  • Extracted from: see the datacards for the French and English datasets.
  • Description: The Claire datasets are composed of transcripts of spoken conversations -- including parliamentary proceedings, interviews, debates, meetings, and free conversations -- as well as some written conversations from theater plays and written chats. The dataset is designed to help downstream performance of models fine-tuned for tasks requiring the comprehension of spontaneous spoken conversation, such as meeting summarization. Each dialogue is split into speech turns, and each speech turn is labeled with the name of the speaker or a unique identifier. See the composition details for the French dataset and the English dataset for a high-level view of the distribution of different types of documents in each dataset.

CroissantAligned

  • Source: croissantllm/croissant_dataset_no_web_data (subset: aligned_36b). License: not specified.
  • Extracted from:
    • Translation pairs: OPUS (99.6% of the data in CroissantAligned). Pairs extracted from OPUS are labeled as "UnbabelFrEn".
    • Thesis abstracts: French thesis abstract pairs. License: ETALAB-Licence-Ouverte-v2.0.
    • Song lyrics: lacoccinelle.
  • Description: CroissantAligned contains samples of parallel French/English (or English/French) data. Data extracted from OPUS takes the form of sentences pairs, where one sentence is in French and the other is in English. OPUS pairs were passed through a custom pipeline designed to select the highest quality translation examples. Selected pairs are labeled "UnbabelFrEn" in the CroissantAligned dataset. The thesis abstract subset contains thesis abstracts paired with translations written by the thesis authors. The song lyrics are translated by contributors to www.lacoccinelle.net. Parallel data are used to boost the multilingual capabilities of models trained on them (Faysse et al.,2024).
  • Pre-processing:
    • Language separation and tagging: The original text field of the Croissant dataset contains a sentence or passage in French or English immediately followed by its translation without any indication of which passage is in which language. The first step was thus to split each text into separate, monolingual passages and tag each passage with the appropriate language code, identified automatically using the langid library (see code details). In the Lucie Training Dataset, the extra metadata field for CroissantAligned contains separate keys, text_fr for French and text_en for English, that stores the texts separately.
    • Random combination of texts prefixed by language: To create the text values, each monolingual text was repaired with its translation, but random separators and various methods of prefixing the text with the language (name or code) were added. This was done as a precaution to prevent models trained on this data from switching languages when generating text and can be seen as a very basic instruction to translate the source (first) text into the target (second) text (see code details).

The goal of the extraction and processing was to generate sentence aligned text for statistical machine translation systems" (www.statmt.org).
  • Pre-processing:
    • Random combination of aligned texts prefixed by language: The same process as used for the CroissantAligned dataset was applied to the EuroparlAligned dataset (see code details). In the Lucie Training Dataset, the extra field in the metadata for EuroparlAligned provides texts in the two languages under the sub-fields text_1 and text_2, and the corresponding language codes under lang_1 and lang_2.

      • Gopher filtering and repetition removal
      • Redpajama document deduplication
    • Removal of personally identifying information (PII): email addresses and ip addresses were replaced with random addresses (see code details).
    • MinHash deduplication was performed on each snapshot and language independantly as proposed in FineWeb. For minhash configuration see code details.

    The Datatrove library was used to perform both filtering and deduplication stages.

  • Extracted from: GitHub via GHarchive. Mixed licenses for source.
  • Description: "The Stack contains over 6TB of permissively-licensed source code files covering 358 programming languages. The dataset was created as part of the BigCode Project, an open scientific collaboration working on the responsible development of Large Language Models for Code (Code LLMs). The Stack serves as a pre-training dataset for Code LLMs, i.e., code-generating AI systems which enable the synthesis of programs from natural language descriptions as well as other from code snippets. This is the near-deduplicated version with 3TB data" (from the dataset card).

Theses

  • Source: Corpus contributed by OpenLLM partners.
  • Extracted from: theses.fr (License: Licence Ouverte / Open Licence version 2.0) and HAL (Open access).
  • Description: A collection of doctoral theses published in France. Dataset containing text retrieved through OCR.
  • Pre-processing:
    • Text cleaning:
      • Title pages about HAL, pages containing a significant fraction of control characters, and duplicate lines were removed (see code details).
      • Because the results of OCR on tables and graphics can give rise to garbage text, the text was cleaned by removing the most suspicious chunks. In particular, a chunk was removed if it was not detected as being written in French, English, Spanish, German or Italian, or if the perplexity of a CCNet Language Model on the chunk was higher than 2000 (see code details). The code to compute CCNET perplexity, parallelizing on parquet files, is available here.
    • Filtering: Texts with fewer than 1000 words or 10000 characters were removed (see code details).

Example use in Python

Load the dataset

Load and iterate over the full dataset using the datasets library:

from datasets import load_dataset

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", split="train", streaming=True)

for sample in dataset:
   
   text = sample["text"]

   # … do something with the text

Iterate over a subset

Several configurations are available to select a language, a source, or both, illustrated in the following examples.

The list of possible configurations can be obtained programmatically:

from datasets import load_dataset_builder

config_names = list(load_dataset_builder("OpenLLM-France/Lucie-Training-Dataset").builder_configs)

print(config_names)

['default', 'en', 'fr', 'de', 'es', 'it', 'de,fr', 'es,en', 'fr,en', 'it,en', 'natural', 'code', 'code-assembly', 'code-c', 'code-c#', 'code-c++', 'code-clojure', 'code-dart', 'code-elixir', 'code-erlang', 'code-fortran', 'code-go', 'code-haskell', 'code-java', 'code-javascript', 'code-julia', 'code-kotlin', 'code-lua', 'code-mathematica', 'code-matlab', 'code-ocaml', 'code-perl', 'code-php', 'code-python', 'code-r', 'code-racket', 'code-ruby', 'code-rust', 'code-scala', 'code-swift', 'code-tex', 'code-typescript', 'AmendementsParlement', 'AmericanStories', 'Claire', 'Claire-en', 'Claire-fr', 'CroissantAligned', 'DiscoursPublics', 'Europarl', 'Europarl-de', 'Europarl-en', 'Europarl-es', 'Europarl-fr', 'EuroparlAligned', 'EuroparlAligned-de,fr', 'EuroparlAligned-es,en', 'EuroparlAligned-fr,en', 'EuroparlAligned-it,en', 'Eurovoc', 'Eurovoc-de', 'Eurovoc-en', 'Eurovoc-es', 'Eurovoc-it', 'FineWebEdu', 'GallicaMonographies', 'GallicaPress', 'Gutenberg', 'Gutenberg-de', 'Gutenberg-en', 'Gutenberg-es', 'Gutenberg-fr', 'Gutenberg-it', 'HAL', 'InterventionsParlement', 'LEGI', 'MathPile', 'OpenData', 'OpenEdition', 'PeS2o', 'PeS2o-s2ag', 'PeS2o-s2orc', 'Pile', 'Pile-DM_Mathematics', 'Pile-FreeLaw', 'Pile-NIH_ExPorter', 'Pile-PhilPapers', 'Pile-StackExchange', 'Pile-USPTO_Backgrounds', 'Pile-Ubuntu_IRC', 'QuestionsEcritesParlement', 'RedPajama', 'RedPajama-de', 'RedPajama-es', 'RedPajama-fr', 'RedPajama-it', 'Stac', 'TheStack', 'Theses', 'Wikipedia', 'Wikipedia-de', 'Wikipedia-en', 'Wikipedia-es', 'Wikipedia-fr', 'Wikipedia-it', 'Wikisource', 'Wiktionary', 'YouTube']

Below are some examples of how to load data from different sources and in different languages.

Load data in French:

from datasets import load_dataset

kwargs = dict(split="train", streaming=True)

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "fr", **kwargs)

Load data where French and English are aligned:

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "fr,en", **kwargs)

Load data corresponding to files with programming languages:

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "code", **kwargs)

Load data in Python:

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "code-python", **kwargs)

Load data from Wikipedia (in all available languages):

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "Wikipedia", **kwargs)

Load data from French pages of Wikipedia (wikipedia.fr):

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "Wikipedia-fr", **kwargs)

Load the Pile dataset:

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "Pile", **kwargs)

Load the subset "PhilPapers" from the Pile dataset:

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", "Pile-PhilPapers", **kwargs)

Load a specific version

You can load a specific version with the datasets Python package using the revision parameter of load_dataset(…):

from datasets import load_dataset

kwargs = dict(split="train", streaming=True)

name = None # or a configuration (e.g. "fr", "code-python", "Wikipedia-fr", "Pile-PhilPapers")

dataset = load_dataset("OpenLLM-France/Lucie-Training-Dataset", name, revision="v1.2", **kwargs)
