Evaluation measures such as recall and precision are a way to assess...

• a system's complexity.

• a system's run time.

• a sytem's importance in the world.

• a system's performance.

Fill in the gap:
Precision checks what percentage of the instances classified as positive by [ ] are correct.

• the tutors

• the gold standard

• the system
