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
Background	4	Focus is on the background surrounding the tin opener.
Background	4	The red region focuses completly over the background in some images and in others it slightly touches the edges of the predicted object.
Background	5	The red is on the background of the can opener.
Background	5	The highlighted visual attributes seems to have missed the object entirely. some images are blank and one image is of a watch not an opener.
Background	5	The red region in the highlighted visual attributes focuses on the background of the can opener.


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