EHRs usually contain heterogeneous information, such as structural data in tabular form and un-structured data in textual notes. Different types of information in EHRs can complement each other and provide a comprehensive picture of a patient\u2019s health status. While there has been a lot of research on the representation learning of structured EHR data, the fusion of different types of EHR data (multimodal fusion) is not well studied. This is mostly because of the complex medical coding systems and the noise and redundancy in the written notes. In this work, we propose a new framework called MINGLE, which effectively integrates both structures and semantics in EHR. Our framework uses a two-level infusion strategy to combine medical concept semantics and clinical note semantics into hypergraph neural networks, which learn the complex interactions between different types of data to generate visit representations for downstream prediction. Experiment results on two EHR datasets, the public MIMIC-III and private CRADLE, show that MINGLE can effectively improve predictive performance by 11.83% relatively, enhancing semantic integration as well as multimodal fusion for structural and textual EHR data.<\/jats:p>","DOI":"10.3233\/shti250941","type":"book-chapter","created":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:35:52Z","timestamp":1754566552000},"source":"Crossref","is-referenced-by-count":7,"title":["Multimodal Fusion of EHR in Structures and Semantics: Integrating Clinical Records and Notes with Hypergraph and LLM"],"prefix":"10.3233","author":[{"given":"Hejie","family":"Cui","sequence":"first","affiliation":[{"name":"Center for Biomedical Informatics Research, Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Fang","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Emory University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ran","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Emory University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuan","family":"Kan","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Emory University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joyce C.","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Emory University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Emory University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","MEDINFO 2025 \u2014 Healthcare Smart \u00d7 Medicine Deep"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SHTI250941","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,7]],"date-time":"2025-08-07T11:35:53Z","timestamp":1754566553000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/SHTI250941"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,8,7]]},"ISBN":["9781643686080"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/shti250941","relation":{},"ISSN":["0926-9630","1879-8365"],"issn-type":[{"value":"0926-9630","type":"print"},{"value":"1879-8365","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,8,7]]}}}
