MTurk Worker Annotations

We now show the responses from five crowdworkers used to annotate this class-feature pair as core or spurious. Workers first denote if the focus of the image is on the main object (core), or a separate or background object (spurious). They also mark their confidence on a scale of 1 to 5, and provide written explanations for their annotation.



Main Focus	Confidence	Explanation
Main Object	5	The main focus is on the missile, and the focus in these images is on some of the parts of the missile.
Main Object	2	Focus is on the exhaust area of the missile or rocket.
Separate Object	4	The red region in the highlighted visual attributes focuses on the flame of a missile that's not a part of the main object.
Main Object	3	The red part seems to be focused on the heated area. its near the bottom of the rocket where the fire/ power is coming from.
Main Object	4	The focus is on the gasses being emitted by the missile.


Votes for core: 4, Votes for spurious: 1. Feature is thus annotated as core for the class.
