Model description

A fine-tuned version of the bsc-bio-ehr-es model on the MEDDOPLACE corpus (subtrack 1) for named geopolitical entities (GPE_NOM), generic geopolitical entities (GPE_GEN), named geographical entities (GEO_NOM), generic geographical entities (GEO_GEN), named facility entities (FAC_NOM), generic facility entities (FAC_GEN), community (COMUNIDAD), language (IDIOMA), transportation (TRANSPORTE), and clinical departments and services (DEPARTAMENTO).

For further information, check the official website.

How to use

⚠ We recommend pre-tokenizing the input text into words instead of providing it directly to the model, as this is how the model was trained. Otherwise, the results and performance might get affected.

A usage example can be found here.

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.

Evaluation

Strict (same class, exact boundary) and overlapping (same class, some overlap) metrics for the MEDDOPLACE Subtrack 1 test set.
