Exploring the Optimal Intervals of Long-Range Clinical Note Language Modeling","arxiv_id":"2211.07713","date":"2022-10-25","proceeding":null,"authors":["Samuel Cahyawijaya","Bryan Wilie","Holy Lovenia","Huan Zhong","MingQian Zhong","Yuk-Yu Nancy Ip","Pascale Fung"],"abstract":"Large pre-trained language models (LMs) have been widely adopted in biomedical and clinical domains, introducing many powerful LMs such as bio-lm and BioELECTRA. However, the applicability of these methods to real clinical use cases is hindered, due to the limitation of pre-trained LMs in processing long textual data with thousands of words, which is a common length for a clinical note. In this work, we explore long-range adaptation from such LMs with Longformer, allowing the LMs to capture longer clinical notes context. We conduct experiments on three n2c2 challenges datasets and a longitudinal clinical dataset from Hong Kong Hospital Authority electronic health record (EHR) system to show the effectiveness and generalizability of this concept, achieving 10\\% F1-score improvement. Based on our experiments, we conclude that capturing a longer clinical note interval is beneficial to the model performance, but there are different cut-off intervals to achieve the optimal performance for different target variables.
