# 🇫🇷 French State Administrations Directory Dataset

This dataset is a processed and embedded version of the public data **Référentiel de l’organisation administrative de l’État** (French State Administrations Directory), published by **DILA** (Direction de l'information légale et administrative) on [data.gouv.fr](https://www.data.gouv.fr/fr/datasets/referentiel-de-lorganisation-administrative-de-letat/).
This information is also available on the official directory website of Service-Public.fr: https://lannuaire.service-public.fr/

The dataset provides semantic-ready, structured and chunked data of French state entities, including organizational details, missions, contact information, and hierarchical links. Each chunk of text is vectorized using the [BAAI/bge-m3](https://huggingface.co/BAAI/bge-m3) embedding model to enable semantic search and retrieval tasks.

## 🛠️ Data Processing Methodology

### 📥 1. Field Extraction

The following fields were extracted and/or transformed from the original JSON:

- **Basic fields**: `chunk_id`, `doc_id`, `name`, `types`, `mission_description`, `additional_information`, `siret`, `siren`, `directory_url`, `modification_date` are directly extracted from JSON attributes.
- **Structured lists**:
  - `addresses`: list of dictionaries with `adresse`, `code_postal`, `commune`, `pays`, `longitude`, and `latitude`.
  - `phone_numbers`, `mails`, `urls`, `social_medias`, `mobile_applications`, `contact_forms`: derived from their respective fields with formatting.
- **People and structure**:
  - `people_in_charge`: list of dictionaries representing staff members or leadership (title, name, rank, etc.).
  - `organizational_chart`, `hierarchy`: structural information within the administration.
- **Other fields**:
  - `opening_hours`: built using a custom function that parses declared time slots into readable strings.
  - `chunk_xxh64`: is the xxh64 hash of the `chunk_text` value. It is useful to determine if the `chunk_text` value has changed from a version to another.

### ✂️ 2. Generation of `chunk_text`

A synthetic text field called `chunk_text` was created to summarize key aspects of each administrative body. This field is designed for semantic search and embedding generation. It includes:

- The entity’s name : `name`
- Its mission statement (if available) : `mission_description`
- Key responsible individuals (formatted using role, title, name, and rank) : `people_in_charge`

There was no need here to split characters here.

### 🧠 3. Embeddings Generation

Each `chunk_text` was embedded using the [**`BAAI/bge-m3`**](https://huggingface.co/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:

```python
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/state-administrations-directory")
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/state-administrations-directory-latest/` folder : 
```python
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="state-administrations-directory-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.
