Annotation

How it is used

Also used for the labels themselves ('the annotations are in a JSON file'). The people who do it are annotators; teams write annotation guidelines and measure how often annotators agree. Often used as a near synonym of labeling.

Example sentences

1. Annotation of 10,000 X-rays took three doctors almost two months.

2. We rewrote the annotation guidelines because annotators disagreed on a third of the examples.
