Transfer Learning based prognostic clinical prediction Framework usingBiomedical NLP

Abstract

In this study, we offer a novel framework for biomedical named entity recognition based on transfer learning using the BioALBERT model. The extraction of a great deal of biomedical knowledge from unstructured texts into organized formats relies heavily on the recognition of biomedical entities in literature, which is a challenging area of study. To implement biological named entity recognition (BioNER), the sequence labeling framework is now the gold standard. The performance of this approach is inconsistent, and it often fails to make full use of the semantic information in the dataset. To have a complete picture of a disease, one must be familiar with its signs and symptoms, medical evaluation, and treatment options. A great deal of medical and scientific work relies on this illness data, including disease diagnosis, consumer health question answering, and the development of medical nomenclature. Instead of approaching the BioNER task as a sequence labeling problem, we present a formulation of the problem as a machine reading comprehension (MRC) issue in this study. Carefully constructed queries can include more prior knowledge into this formulation, and unlike conditional random fields (CRF), no decoding methods are required. Although pre-trained language models like BERT have shown success in extracting syntactic, semantic, and world knowledge from text, we find that they can be further enhanced by specialized information like knowledge about symptoms, diagnosis, and other elements of an illness. Therefore, we combine ALBERT with medical knowledge to enhance BioNER. In specifically, we evaluate a new approach to training that incorporates illness knowledge infusion on BioALBERT. By showing that these models can be enhanced in nearly all cases, the experiments conducted for this task indicate the efficacy of disease knowledge infusion.
