  26. T-GreC at LLMs4OL 2025 Task B: A Report on Term-Typing Task of OBI dataset using LLM with k-Nearest Neighbors

    ISSN： 2749-5841

    More details Close

    This report presents an approach that combines large language models' (LLMs) embedding with k-nearest neighbors (k-NN) for the term-typing task on the OBI (Ontology for Biomedical Investigations) dataset. We investigate the effectiveness of transformer models namely PubMedBERT, BioBERT, DeBERTa-v3, and RoBERTa with k-NN classification using the embedding of each respective model. Our experimental results demonstrate that fine-tuned LLMs not only have the capability to do term typing on their own but also can learn effective embeddings that are exploitable by k-NN for solving the task, with RoBERTa achieving the highest F1 score of 0.827 and k-NN using embedding from the model with score of 0.862. The study reveals that embeddings from transformer models, when used as semantic representations for similarity-based method, improve classification accuracy in this specific case.
