MeSHup: Corpus for Full Text Biomedical Document Indexing

1 code implementation LREC 2022 Xindi Wang, Robert E. Mercer, Frank Rudzicz

Medical Subject Heading (MeSH) indexing refers to the problem of assigning a given biomedical document with the most relevant labels from an extremely large set of MeSH terms.

Enhancing disease detection in radiology reports through fine-tuning lightweight LLM on weak labels

no code implementations25 Sep 2024 Yishu Wei, Xindi Wang, Hanley Ong, Yiliang Zhou, Adam Flanders, George Shih, Yifan Peng

These findings demonstrate the potential of fine-tuning LLMs with synthetic labels, offering a promising direction for future research on LLM specialization in the medical domain.

Multi-stage Retrieve and Re-rank Model for Automatic Medical Coding Recommendation

no code implementations29 May 2024 Xindi Wang, Robert E. Mercer, Frank Rudzicz

In this paper, we leverage a multi-stage ``retrieve and re-rank'' framework as a novel solution to ICD indexing, via a hybrid discrete retrieval method, and re-rank retrieved candidates with contrastive learning that allows the model to make more accurate predictions from a simplified label space.

Investigating the Learning Behaviour of In-context Learning: A Comparison with Supervised Learning

1 code implementation28 Jul 2023 Xindi Wang, YuFei Wang, Can Xu, Xiubo Geng, BoWen Zhang, Chongyang Tao, Frank Rudzicz, Robert E. Mercer, Daxin Jiang

Large language models (LLMs) have shown remarkable capacity for in-context learning (ICL), where learning a new task from just a few training examples is done without being explicitly pre-trained.

Medical Subject Heading (MeSH) indexing refers to the problem of assigning a given biomedical document with the most relevant labels from an extremely large set of MeSH terms.

KenMeSH: Knowledge-enhanced End-to-end Biomedical Text Labelling

1 code implementation ACL 2022 Xindi Wang, Robert E. Mercer, Frank Rudzicz

Currently, Medical Subject Headings (MeSH) are manually assigned to every biomedical article published and subsequently recorded in the PubMed database to facilitate retrieving relevant information.

Exploring Text Specific and Blackbox Fairness Algorithms in Multimodal Clinical NLP

1 code implementation EMNLP (ClinicalNLP) 2020 John Chen, Ian Berlot-Attwell, Safwan Hossain, Xindi Wang, Frank Rudzicz

Clinical machine learning is increasingly multimodal, collected in both structured tabular formats and unstructured forms such as freetext.

End-to-end Named Entity Recognition and Relation Extraction using Pre-trained Language Models

1 code implementation20 Dec 2019 John Giorgi, Xindi Wang, Nicola Sahar, Won Young Shin, Gary D. Bader, Bo wang

In this paper, we propose a neural, end-to-end model for jointly extracting entities and their relations which does not rely on external NLP tools and which integrates a large, pre-trained language model.
