EriBERTa: A Bilingual Pre-Trained Language Model for Clinical Natural Language Processing

Abstract: The utilization of clinical reports for various secondary purposes, including health research and treatment monitoring, is crucial for enhancing patient care. NLP tools have emerged as valuable assets for extracting and processing relevant information from these reports. However, the availability of specialized LLMs for the clinical domain in Spanish has been limited. In this paper, we introduce EriBERTa, a bilingual domain-specific LLM pre-trained on extensive medical and clinical corpora. We demonstrate that EriBERTa outperforms previous Spanish LLMs in the clinical domain, showcasing its superior capabilities in understanding medical texts and extracting meaningful information. Moreover, EriBERTa exhibits promising transfer learning abilities, allowing for knowledge transfer from one language to another. This aspect is particularly beneficial given the scarcity of Spanish clinical data.
