"""# Demo de Retrieval-Augmented Generation per documents legals | |
🔍 **Retrieval-Augmented Generation** (RAG) és una tecnologia de IA que permet interrogar un repositori de documents amb preguntes | |
en llenguatge natural, i combina tècniques de recuperació d'informació avançades amb models generatius per redactar una resposta | |
fent servir només la informació existent en els documents del repositori. | |
🎯 **Objectiu:** Aquest és un primer demostrador amb la normativa vigent publicada al Diari Oficial de la Generalitat de Catalunya, en el | |
repositori del EADOP (Entitat Autònoma del Diari Oficial i de Publicacions). Aquesta primera versió explora prop de 2000 documents en català, | |
i genera la resposta fent servir el model Flor6.3b entrenat amb el dataset de QA generativa BSC-LT/RAG_Multilingual. | |
⚠️ **Advertencies**: Primera versió experimental. El contingut generat per aquest model no està supervisat i pot ser incorrecte. | |
Si us plau, tingueu-ho en compte quan exploreu aquest recurs. | |
