Groundbreaking Solutions Utilizing Large Language Model-Based Natural Language Processing


In an investigation aimed at grasping the nuanced experiences of cancer patients and their caregivers, we delved into vast data of online posts using advanced natural language processing (NLP) techniques. Our approach involved dissecting elements like medications, illnesses, and treatments into standardized frameworks. By employing entity relationship mapping, we untangled the connections among these elements as described in user-generated content.

Drawing upon Large Language Models (LLMs), we distilled the texts into narratives centered around diseases. Our study illuminates the emotional and informational needs of patients and caregivers and proposes a practical solution to address these needs effectively through advanced technology.

We are in the early stages of developing a chatbot that can effectively utilize our solution and provide accurate and empathetic responses to common inquiries from patients and caregivers.
