+# Model Card for er-mdeberta-v3-base
+This relation extraction model extracts intervention-associated relationships, temporal relations, negation/speculation and others relevant
+for clinical trials.
+The model achieves the following results on the test set (when trained with the training and development set; results are averaged over 5 evaluation rounds):
+- Precision: 0.886 (±0.003)
+- Recall: 0.857 (±0.007)
+- F1: 0.869 (±0.005)
+- Accuracy: 0.911 (±0.003)
+## Model description
+This model adapts the pre-trained model [mdeberta-v3-base](https://huggingface.co/microsoft/mdeberta-v3-base).
+It is fine-tuned to conduct relation extraction on Spanish texts about clinical trials.
+The model is fine-tuned on the [Clinical Trials for Evidence-Based-Medicine in Spanish corpus](http://www.lllf.uam.es/ESP/nlpdata/wp2/).
+If you use this model, please, cite as follows:

+## Training and evaluation data
+The data used for fine-tuning are the [Clinical Trials for Evidence-Based-Medicine in Spanish corpus](http://www.lllf.uam.es/ESP/nlpdata/wp2/) version 3 (annotated with semantic relationships).
+It is a collection of 1200 texts about clinical trials studies and clinical trials announcements:
+- 500 abstracts from journals published under a Creative Commons license, e.g. available in PubMed or the Scientific Electronic Library Online (SciELO)
+- 700 clinical trials announcements published in the European Clinical Trials Register and Repositorio Español de Estudios Clínicos
