The state-of-the-art performance of large language models (LLMs) in medical natural language (NLP) tasks, including medical query answering, summarization of clinical notes, and generation of medical reports has led to the development of a large number of application studies. However, many of these studies have also identified the key role of human input in generating accurate results with significant efforts focused on identifying an effective mechanism to elicit, model, and integrate human medical expertise in optimizing LLMs. In this paper, we introduce a new approach based on biomedical ontologies as a knowledge model to significantly improve the performance of LLMs in biomedical natural language processing (NLP) applications. Specifically, we focus on a rare pediatric epilepsy called Dravet syndrome (DS) which there is very limited understanding about the mechanisms that result in seizure and demonstrate the effectiveness of a unique epilepsy ontology in improving the accuracy of results. The results of this study create a new pathway for integrating human expertise in LLMs to support high accuracy and consistent results in medical applications.
