It also highlights the model's capability in identifying protein-coding regions within DNA sequences, despite the need for expert validation due to AI-generated errors and undisclosed training data sources.
- Biomedical Text Mining: In text mining, ChatGPT shows promising, albeit variable, performance compared to state-of-the-art models, especially in question answering and document classification tasks. However, it struggles with specific tasks like SNP and alignment questions, where domain-optimized models prevail. The paper also touches on the use of ChatGPT in constructing biomedical knowledge graphs, indicating an underperformance in generating novel entity relationships.
- Drug Discovery: The application of ChatGPT in drug discovery is explored, where it aids in the identification of drug-disease associations and drug-drug interactions. Yet, its effectiveness varies, underscoring the need for human oversight. The paper cites examples demonstrating the potential of ChatGPT, facilitated by human-in-the-loop methodologies, for refining drug discovery processes.
- Biomedical Image Understanding: This section underscores the capability of GPT-4V, a variant of ChatGPT, in image-related tasks within the biomedical domain, such as medical image classification and analysis. While performance levels are remarkable, the model encounters challenges in accurately interpreting closely located text and factual details in scientific figures.
- Bioinformatics Programming: The concept of "prompt bioinformatics" is introduced, demonstrating ChatGPT's utility in generating code for bioinformatics analysis. However, the model's limitations in writing longer, complex code necessitate methods to ensure result reproducibility and acknowledge the evolving nature of prompt engineering and model upgrades.
- Biomedical Database Access and Education: The paper explores the transformation ChatGPT brings to database querying and bioinformatics education. It showcases the model's effectiveness in natural language to SQL/SPARQL query translation and highlights the educational implications, including the need for innovative evaluation strategies to combat overreliance on AI.
