model_5M

This model is a fine-tuned version of gsarti/it5-large on a dataset of Common Procurement Vocabulary (CPV) codes.

Model description

The model is trained on 3.2M pairs of Italian tender descriptions and the corresponding CPV code.

Here an example:

{"source": "lavori lavori di pavimentazione delle vie san martino e santa Maddalena", "target": "45262321-7 - lavori di pavimentazione"}

Intended uses & limitations

This model can generate a CPV code given an Italian tender description.

Training and evaluation data

Training data are taken form the ANAC website.
