Table 3.

Summary of cTAKES annotations by type unique identifier (TUI). cTakes identified a total of 249 unique text strings. Of these, 128 were classified as disease/disorder mentions from six different TUIs and 121 were sign/symptom mentions from four different TUIs. Each annotation was compared to the manual annotation list generated by the radiologists (the gold-standard set). A match was assigned if the string was identical to or partially overlapped a term in the manual annotation set. No match was assigned when the cTakes annotation had no overlap with a manual annotation. TUI041 and TUI184 (italics) were excluded from subsequent analyses because of their high false-positive rate
