Study: Evaluation design impacts MeSH feature performance gap

A new study published on arXiv investigates the impact of evaluation design on the performance gap between expert-assigned and automatically generated Medical Subject Headings (MeSH) when used as features in classification tasks. The research compared a bag-of-words logistic regression model with BiomedBERT, a domain-specific language model, on the Cohen benchmark for drug-class identification. Findings indicate that the observed gap between expert and auto-assigned MeSH can vary significantly based on evaluation methodologies, such as corpus size and cross-validation folds. The study also noted that transformer models like BiomedBERT may face token limits with appended MeSH terms, potentially affecting their performance. AI

    Evaluation design conditions the expert-vs-auto MeSH gap: a controlled comparison of bag-of-words and BiomedBERT on the Cohen benchmark

    arXiv:2607.21685v1 Announce Type: new Abstract: A systematic review begins with someone reading thousands of abstracts to identify the few that are relevant, and classifiers are used to prioritise that reading. Their inputs are often augmented with Medical Subject Headings (MeSH)…
