# French Legal Document Vector Database |
|
|
## Overview of DILA Repository Datasets |
|
|
|
|
|
This set is a collection of four vector databases which contains documents produced by various French governmental institutions made available by the DILA (Direction de l'Information légale et administrative) repository, |
|
|
|
|
|
The original sources can be accessed at: https://echanges.dila.gouv.fr/OPENDATA/ |
|
|
|
|
|
Embeddification has been done with one of the best multilingual embedding model to date for administrative French, BGE-M3-Large |
|
|
|
|
|
The vector databases have been processed with lancedb. Lancedb include the following features: |
|
|
* Support for BGE-M3-Large with varying context length. |
|
|
* Combination of queries including semantic, pure text and hybrid. For administrative texts best results are to be obtained with hybrid. |

## Technical Implementation |
|
|
|
|
|
### Data Processing |
|
|
- Original format: XML within a complex nested folder structure |
|
|
- Converted to: Parquet format with relevant metadata in separate columns |
|
|
- Embedding model: BGE-M3-Large |
|
|
- Chunk size: Approximately 350 words for RAG system compatibility |
|
|
- Storage: LanceDB databases for improved retrieval methods (e.g., hybrid search) |
|
|
- The "text" column has been vectorized and stored in LanceDB databases |
|
|
- The main title of each document is in the "name" column |
|
|
- All other columns have been preserved as metadata for each entry |
|
|
|
|
|
