## Model description

The **multiner** is a Named Entity Recognition (NER) model for the Catalan language fine-tuned from the [BERTa] model, a [RoBERTa](https://arxiv.org/abs/1907.11692) base model pre-trained on a medium-size corpus collected from publicly available corpora and crawlers (check the BERTa model card for more details).

It has been trained with a dataset that contains 9 main types and 52 subtypes on all kinds of short texts, with almost 59K documents. 

## Intended uses and limitations


## How to use


## Limitations and bias
At the time of submission, no measures have been taken to estimate the bias embedded in the model. However, we are well aware that our models may be biased since the corpora have been collected using crawling techniques on multiple web sources. We intend to conduct research in these areas in the future, and if completed, this model card will be updated.

## Training
We used the NER dataset in Catalan called [Catalan Entity Identification and Linking](https://huggingface.co/datasets/crodri/ceil) for training and evaluation.

## Evaluation
