A tool designed for legal professionals
A specialized neural translation engine for the legal sector, offering accuracy and reliability.
Layered architecture
- General training
The engine is first trained to translate generalist legal texts such as doctrine or articles, taking into account the terminological variations and nuances specific to each legal system.
- Specialized training
Once the basic training has been completed, the engine is duplicated, and each new engine is fed with specialized documents from a particular field of law. The general-purpose engine gives rise to several engines, each with its own specialty.
- Terminology training
Enrichment with knowledge of specific areas of law, such as commercial law, criminal law, civil law, etc.
