Ontology-Guided Query Expansion for Biomedical Document Retrieval using Large Language Models
Zabir Al Nazi, Vagelis Hristidis, Aaron Lawson McLean +2
Effective Question Answering (QA) on large biomedical document collections requires effective document retrieval techniques. The latter remains a challenging task due to the domain…
Progressive Query Expansion for Retrieval Over Cost-constrained Data Sources
Muhammad Shihab Rashid, Jannat Ara Meem, Yue Dong +1
Query expansion has been employed for a long time to improve the accuracy of query retrievers. Earlier works relied on pseudo-relevance feedback (PRF) techniques, which augment a q…
