Amount of True Positives (TP) and Precision obtained at selected subsets of validated entities corresponding to 25%, 50% and 75% of the total amount on annotations performed by each tool (Method), using validation calculated using the semantic similarity measure indicated in Measure. For this evaluation was used the document-wide as text window.
