🇫🇷 Data.gouv.fr Datasets Catalog

This dataset contains a processed and embedded version of the catalog of datasets published on data.gouv.fr, the French open data platform. The dataset was published by data.gouv.fr on the dedicated dataset page.

It includes rich metadata about each public dataset: title, URL, publisher organization, description, tags, licensing, update frequency, usage metrics, and more. The dataset provides semantic-ready and structured for semantic indexing and retrieval.

Each chunk has been embedded using the BAAI/bge-m3 model, making this catalog ready for search, classification, or retrieval-augmented generation (RAG) pipelines.

🛠️ Data Processing Methodology

📥 1. Field Extraction

The original dataset was retrieved directly from the official dedicated dataset page. This dataset only includes data.gouv.fr datasets that have at least a 100 characters description to remove as much noise as possible from incomplete datasets.

✂️ 2. Text Chunking

The chunk_text field was created by combining the title, organization name, description.

The description was cropped to a maximum length of +- 1000 characters. The Langchain's RecursiveCharacterTextSplitter function was used to crop the description.

The parameters used are :

• chunk_size = 1000 (in order to limit as much noise as possible)
• chunk_overlap = 20
• length_function = len

Then, only the first splitted text was keeped. Which leads to have a cropped description of a maximum of +- 1000 characters.

🧠 3. Embedding Generation

Each chunk_text was embedded using the BAAI/bge-m3 model. The resulting embedding vector is stored in the embeddings_bge-m3 column as a string, but can easily be parsed back into a list[float] or NumPy array.

📌 Embeddings Notice

⚠️ The embeddings_bge-m3 column is stored as a stringified list (e.g., "[-0.03062629,-0.017049594,...]"). To use it as a vector, you need to parse it into a list of floats or NumPy array. For example, if you want to load the dataset into a dataframe by using the datasets library:

import pandas as pd
import json
from datasets import load_dataset
# The Pyarrow library must be installed in your Python environment for this example. By doing => pip install pyarrow

dataset = load_dataset("AgentPublic/data-gouv-datasets-catalog")
df = pd.DataFrame(dataset['train'])
df["embeddings_bge-m3"] = df["embeddings_bge-m3"].apply(json.loads)

Otherwise, if you have already downloaded all parquet files from the data/data-gouv-datasets-catalog-latest/ folder :

import pandas as pd
import json
# The Pyarrow library must be installed in your Python environment for this example. By doing => pip install pyarrow

df = pd.read_parquet(path="data-gouv-datasets-catalog-latest/") # Assuming that all parquet files are located into this folder
df["embeddings_bge-m3"] = df["embeddings_bge-m3"].apply(json.loads)

You can then use the dataframe as you wish, such as by inserting the data from the dataframe into the vector database of your choice.
