Control tasks

This indicator shows the average ratio of control tasks to other tasks within per task suites. A large percentage of control tasks lets you improve the quality but, at the same time, it may make labeling more expensive.

How to calculate

P_{control} = \frac{T_{control}}{T_{total}}\times100

where:

$P_{control}$ is the percentage of control tasks.
$T_{control}$ is the number of control tasks.
$T_{total}$ is the total number of tasks.

The indicator estimation criteria depends on the pool type.
