Latent Knowledge as a Predictor of Fact Acquisition in Fine-Tuned Large Language Models

Daniel B. Hier, Tayo Obafemi-Ajayi

Large language models store biomedical facts with uneven strength after pretraining: some facts are present in the weights but are not reliably accessible under deterministic decod…

From Memorization to Generalization: Fine-Tuning Large Language Models for Biomedical Term-to-Identifier Normalization

Suswitha Pericharla, Daniel B. Hier, Tayo Obafemi-Ajayi

Effective biomedical data integration depends on automated term normalization, the mapping of natural language biomedical terms to standardized identifiers. This linking of terms t…

Predicting Failures of LLMs to Link Biomedical Ontology Terms to Identifiers Evidence Across Models and Ontologies

Daniel B. Hier, Steven Keith Platt, Tayo Obafemi-Ajayi

Large language models often perform well on biomedical NLP tasks but may fail to link ontology terms to their correct identifiers. We investigate why these failures occur by analyz…

Efficient Standardization of Clinical Notes using Large Language Models

Daniel B. Hier, Michael D. Carrithers, Thanh Son Do +1

Clinician notes are a rich source of patient information but often contain inconsistencies due to varied writing styles, colloquialisms, abbreviations, medical jargon, grammatical…

Mapping Biomedical Ontology Terms to IDs: Effect of Domain Prevalence on Prediction Accuracy

Thanh Son Do, Daniel B. Hier, Tayo Obafemi-Ajayi

This study evaluates the ability of large language models (LLMs) to map biomedical ontology terms to their corresponding ontology IDs across the Human Phenotype Ontology (HPO), Gen…

A Simplified Retriever to Improve Accuracy of Phenotype Normalizations by Large Language Models

Daniel B. Hier, Thanh Son Do, Tayo Obafemi-Ajayi

Large language models (LLMs) have shown improved accuracy in phenotype term normalization tasks when augmented with retrievers that suggest candidate normalizations based on term d…

High Throughput Phenotyping of Physician Notes with Large Language and Hybrid NLP Models

Syed I. Munzir, Daniel B. Hier, Michael D. Carrithers

Deep phenotyping is the detailed description of patient signs and symptoms using concepts from an ontology. The deep phenotyping of the numerous physician notes in electronic healt…
