EriBERTa-clinical-trials-attributes

This named entity recognition model detects the following types of medical attributes:

• Experiencer:

  • Patient: e.g. paciente
  • Family_member: e.g. padre
  • Other: e.g. cirujano

• Event temporality:

  • Future: e.g. cirugía pendiente
  • History_of: e.g. antecedentes de migraña

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: 0.890 (±0.007)
• Recall: 0.848 (±0.008)
• F1: 0.868 (±0.002)
• Accuracy: 0.989 (±0.001)

Model description

This model adapts the pre-trained model EriBERTa-base, presented in De la Iglesia et al. (2023). It is fine-tuned to conduct medical named entity recognition on Spanish texts about clinical trials. The model is fine-tuned on the CT-EBM-ES corpus (Campillos-Llanos et al. 2021) vs 2.

Training and evaluation data

The data used for fine-tuning are the Clinical Trials for Evidence-Based-Medicine in Spanish corpus vs 2. 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

Training procedure

Training hyperparameters

The following hyperparameters were used during training:

• learning_rate: 2e-05
• train_batch_size: 16
• eval_batch_size: 16
• seed: we used different seeds for 5 evaluation rounds, and uploaded the model with the best results
• optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
• lr_scheduler_type: linear
• num_epochs: average 16.40 epochs (±3.36); trained with early stopping if no improvement after 5 epochs (early stopping patience: 5)

Training results (test set; average and standard deviation of 5 rounds with different seeds)
