Abstract:

Automating the generation of an accurate summary from clinical reports is crucial in saving clinician's time, improving accuracy, and mitigating potential errors. To this end, we propose a sequence-to-sequence abstractive summarization model augmented with domain-specific ontological information to enhance content selection and summary generation. We apply our method to a dataset of radiology reports and show that it significantly outperforms the current state-of-the-art on this task in terms of ROUGE scores. Extensive human evaluation conducted by a radiologist further indicates that this approach yields summaries that are less likely to omit important details, without sacrificing readability or accuracy.
