The field of medical research is witnessing significant advancements in the development of knowledge graphs and large language models. These innovations are transforming the way medical information is represented, retrieved, and utilized. Recent studies have focused on creating knowledge graphs that integrate medical ontologies with clinical data, enabling robust code embeddings and improved predictive outcomes. The integration of large language models with these knowledge graphs has shown great promise in uncovering disease relationships, predicting clinical outcomes, and enhancing clinically-driven missing data recovery algorithms. Noteworthy papers in this area include: H-DDx, which introduces a hierarchical evaluation framework for differential diagnosis, and KEEP, which presents an efficient framework for integrating medical ontologies with clinical data. These developments have the potential to revolutionize the field of medical research, enabling more accurate diagnoses, personalized medicine, and hypothesis formulation in cognitive neuroscience.
