Annotation of Chest Radiology Reports for Indexing and Retrieval
Annotation of MEDLINE citations with controlled vocabulary terms improves the quality of retrieval results. Due to variety in descriptions of similar clinical phenomena and abundance of negation and uncertainty, annotation of clinical radiology reports for subsequent indexing and retrieval with a search engine is even more important. Provided with an opportunity to add about 4,000 radiology rep...
