Title:

Advancing Named Entity Recognition (NER) in Biomedical Literature Using Hybrid Deep Learning Approaches

1. Introduction

Generally, the biomedical domain has a wide range of text-based data like clinical documents, logs, and scientific papers. For medical-based exploration and decision-making, it is important to retrieve essential data in an effective way. One of the major missions in the medical domain is Named Entity Recognition (NER) that carries out various processes such as detection and classification of biomedical objects into various types like genes, diseases, and chemicals. On the basis of various writing patterns and unclear wordings, this biomedical NER task is examined as still difficult.

For the mission of biomedical NER, this project focuses on the creation of a hybrid deep learning-based model, which integrates several frameworks’ efficiencies. Accomplishing advanced outcomes and enhancing entity recognition are the major concentrations of this research plan.
