File structure

Each .csv file provides the mistake annotation for an assembly sequence.

• There are 328 sequences in total.
• Each annotation contains:
  • start and end timestamps
  • verb (attach, detach)
  • two working objects (this, that)
  • mistake label
  • remark (if any)

Example Annotation

For the assembly sequence nusar-2021_action_both_9033-c02a_9033_user_id_2021-02-04_140532.csv

• 9033 is the actor while c02a is the toy id.
• wrong order : this action is an ordering mistake
• previous one is mistake : this action is also an ordering mistake but is caused by the preceding ordering mistakes in the context
• shouldn't have happened : this detach action is unnecessary
• wrong position : the two parts are not attached at their correct position
