CurateGPT: A flexible language-model assisted biocuration tool

Effective data-driven biomedical discovery requires data curation: a time-consuming process of finding, organizing, distilling, integrating, interpreting, annotating, and validating diverse information into a structured form suitable for databases and knowledge bases. Accurate and efficient curation of these digital assets is critical to ensuring that they are FAIR, trustworthy, and sustainable. Unfortunately, expert curators face significant time and resource constraints. The rapid pace of new information being published daily is exceeding their capacity for curation. Generative AI, exemplified by instruction-tuned large language models (LLMs), has opened up new possibilities for assisting human-driven curation. The design philosophy of agents combines the emerging abilities of generative AI with more precise methods. A curator's tasks can be aided by agents for performing reasoning, searching ontologies, and integrating knowledge across external sources, all efforts otherwise requiring extensive manual effort. Our LLM-driven annotation tool, CurateGPT, melds the power of generative AI together with trusted knowledge bases and literature sources. CurateGPT streamlines the curation process, enhancing collaboration and efficiency in common workflows. Compared to direct interaction with an LLM, CurateGPT's agents enable access to information beyond that in the LLM's training data and they provide direct links to the data supporting each claim. This helps curators, researchers, and engineers scale up curation efforts to keep pace with the ever-increasing volume of scientific data.

An evaluation of GPT models for phenotype concept recognition

Objective: Clinical deep phenotyping plays a critical role in both the diagnosis of patients with rare disorders as well as in building care coordination plans. The process relies on modelling and curating patient profiles using ontology concepts, usually from the Human Phenotype Ontology. Machine learning methods have been widely adopted to support this phenotype concept recognition task. With the significant shift in the use of large language models (LLMs) for most NLP tasks, herewithin, we examine the performance of the latest Generative Pre-trained Transformer (GPT) models underpinning ChatGPT in clinical deep phenotyping. Materials and Methods: The experimental setup of the study included seven prompts of various levels of specificity, two GPT models (gpt-3.5 and gpt-4.0) and an established gold standard for phenotype recognition. Results: Our results show that, currently, these models have not yet achieved state of the art performance. The best run, using few-shots learning, achieved 0.41 F1 score, compared to a 0.62 F1 score achieved by the current best in class tool. Conclusion: The non-deterministic nature of the outcomes and the lack of concordance between different runs using the same prompt and input makes the use of these LLMs in clinical settings problematic.
