| 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. |
