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	4	Focus is on the branch on which the brambling is sitting.
Separate Object	5	The main object is an brambling, fringilla montifringilla, a bird. the focus of the red region on the highlighted visual attributes is on the tree branch's, showing something that's not relevant for the visual attributes since the main object is an brambling, fringilla montifringilla, a bird. because of that, i choose to focus is on some other object (not a part of the main object).
Separate Object	3	Red focus is on the tree.
Separate Object	5	The focus is not a part of the main object.
Background	5	The red parts are focused on the branches where the birds are


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