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

Collection-Specific Modifications

DOLE, CONSTIT, and CNIL

• "name" column content prepended to each "text" entry

CNIL-Specific

• Filtered to retain only entries with "VIGUEUR" status in etat_juridique column

LEGI-Specific

• "name" column created by concatenating "titre" and "article" fields
• "name" column content prepended to each "text" entry
• Filtered to retain only entries with "VIGUEUR" or "VIGUEUR_DIFF" status in etat_value column
