Adapting Abstract Meaning Representation Parsing to the Clinical Narrative -- the SPRING THYME parser
This work addresses the need for structured semantic representations in clinical narratives to enhance interpretability and usability, but it is incremental as it adapts existing methods to a new domain.
The paper tackled the problem of parsing clinical notes into Abstract Meaning Representation (AMR) structures by adapting a state-of-the-art AMR parser to the clinical domain, achieving an F1 score of 88% on a colon cancer dataset from the THYME corpus.
This paper is dedicated to the design and evaluation of the first AMR parser tailored for clinical notes. Our objective was to facilitate the precise transformation of the clinical notes into structured AMR expressions, thereby enhancing the interpretability and usability of clinical text data at scale. Leveraging the colon cancer dataset from the Temporal Histories of Your Medical Events (THYME) corpus, we adapted a state-of-the-art AMR parser utilizing continuous training. Our approach incorporates data augmentation techniques to enhance the accuracy of AMR structure predictions. Notably, through this learning strategy, our parser achieved an impressive F1 score of 88% on the THYME corpus's colon cancer dataset. Moreover, our research delved into the efficacy of data required for domain adaptation within the realm of clinical notes, presenting domain adaptation data requirements for AMR parsing. This exploration not only underscores the parser's robust performance but also highlights its potential in facilitating a deeper understanding of clinical narratives through structured semantic representations.
