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	Q1: the red regions on all 5 images have corn (main object) as its main focus. there is no image with a red region overlapping with an item different from the main one, and on images where a red region overlaps with the background (1, 4 and 5) the main focus is clearly on corn, and not the background.
Main Object	5	The focus of this is on the main object's body, corn
Main Object	5	Focus is on the main object.
Main Object	4	Focus is on the corn.
Main Object	5	The red region focuses mainly on the predicted object but spreads slightly to the background on the edges.


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