Writing habits and telltale neighbors: analyzing clinical concept usage patterns with sublanguage embeddings (D19-62)
Copied to clipboard
| Challenge: | Existing biomedical concepts may have multiple, often non-compositional surface forms, making them difficult to analyze using lexical occurrence alone. |
| Approach: | They propose a method for characterizing usage patterns of clinical concepts among different document types by embedding concepts on clinical documents of different types and measuring their nearest neighborhood structures. |
| Outcome: | Experiments on the MIMIC-III corpus show that the proposed method captures clinically relevant differences in concept usage while correcting for noise in embedding learning. |
