RDscan: Extracting RNA-disease relationship from the literature based on pre-training model

Year: 2024

Type: article

Abstract: With the rapid advancements in molecular biology and genomics, a multitude of connections between RNA and diseases has been unveiled, making the efficient and accurate extraction of RNA-disease relationships (RD relationships) from extensive biomedical literature crucial for advancing research in this field. This study introduces RDscan, a novel text mining method developed based on the pre-training and fine-tuning strategy, aimed at automatically extracting RD-related information from a vast corpus of literature using pre-trained biomedical large language models. Initially, we constructed a dedicated RD corpus, comprising 2,082 positive and 2,000 negative statements, alongside an independent test dataset for training and evaluating RDscan. Subsequently, by fine-tuning the Bioformer and BioBERT pre-trained models, RDscan demonstrated exceptional performance in text classification and named entity recognition (NER) tasks. In 5-fold cross-validation, RDscan significantly outperformed traditional machine learning methods. In summary, RDscan represents the first text mining tool specifically designed for RD relationship extraction, and is freely available at https://github.com/ZhangCellab/RDScaning.
