Task: Question Generation
Input (English): We compare the performance of translation approaches based on four metrics:

[align=left,leftmargin=0em,labelsep=0.4em,font=]

As in BIBREF20 , EM is 1 if a predicted plan matches exactly the ground truth; otherwise it is 0.

The harmonic average of the precision and recall over all the test set BIBREF26 .

The minimum number of insertions, deletions or swap operations required to transform a predicted sequence of behaviors into the ground truth sequence BIBREF27 .

GM is 1 if a predicted plan reaches the ground truth destination (even if the full sequence of behaviors does not match exactly the ground truth). Otherwise, GM is 0.
Output (English): What evaluation metrics are used?
