italian-laws-topic-extraction

Model Description

A Mistral-7B-instruct-v0.1 model to extract the topics from a text of Italian law articles (titles). It is fine-tuned over a set of 74k high quality law title-topics pairs, which were initially obtained from the application of a larger model (Mixtral8x22) and then pre-processed to increase the quality of the training set by means of heuristics that aggregate slighlty different topics and allow the fine-tuned model to achieve an higher diversity
