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
Separate Object	5	Images are mainly focused on other objects like pot.
Separate Object	4	Pot is not a part of potter's wheel
Separate Object	4	Out of the 5 images, only number 1 has the red region focusing on the main object. images 3 and 5 have the red region focusing on other objects sitting on top of the main one, and images 2 and 4 don't show the main object, so a red region couldn't focus on it. there is no significant overlap in between a red region and the background in any of the 5 images.
Separate Object	4	Focus is on pot, not on potter's wheel
Separate Object	4	Highlighted area is focused more on the clay pot itself, and not the actual potter's wheel.


Votes for core: 0, Votes for spurious: 5. Feature is thus annotated as spurious for the class.
