Description Knowledge Graphs (KGs) are receiving growing interest as a knowledge representation framework to shape the interconnected nature of biomedical data, representing heterogeneous relationships between diagnoses, related treatments, drugs, and associated effects.
The capacity to extract information from textual content and map such information to KGs is a critical task in Natural Language Processing (NLP) for building intelligent advisory systems. More precisely, this task is known as Named Entity Disambiguation (NED), and it allows to map named entities mentioned in the text, e.g., diagnoses and medicines, to the related KG entities, e.g., “Type 2 Diabetes” and “Insulin.”
Despite the widespread success of Large-scale Language Models (LLMs) in NLP tasks, there are many opportunities to leverage the structural knowledge in KG for NED. The thesis will allow the student to develop new approaches in this field by combining hybrid strategies (LLMs + KG) to create useful NLP-based biomedical tools. In particular, the student will investigate which KG features may have the most significant impact in this context.
The thesis proposal is in collaboration with Graph Aware S.r.l. company. The interaction with company will be conducted both remotely and physically at the Nexa Center for Internet & Society.
