A Cross-document Coreference Dataset for Longitudinal Tracking across Radiology Reports (2022.lrec-1)
Copied to clipboard
| Challenge: | Oftentimes, these findings and devices are referred to multiple times in a single report and are also referred across different reports of a patient. |
| Approach: | They propose a new cross-document coreference resolution (CDCR) dataset for identifying co-referring radiological findings and medical devices across a patient's radiology reports. |
| Outcome: | The proposed dataset contains 5872 mentions (findings and devices) spanning 638 MIMIC-III radiology reports across 60 patients, covering multiple imaging modalities and anatomies. |

| Challenge: | Existing framework for encoding spatial language in radiology is based on frame semantics . |
| Approach: | They propose a framework for encoding spatial language in radiology based on frame semantics and a corpus of 400 radiology reports annotated with spatial trigger expressions and contextual information. |
| Outcome: | The proposed framework is based on the existing SpatialNet representation in the general domain and is able to generate more accurate representations of spatial language in radiology. |
