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 Object	5	The main object is a pelican, a bird. the focus of the red region on the highlighted visual attributes is on the bird's head and body, showing its main parts. because of that, i choose that focus is on some part of the main object.
Main Object	3	Focus is on pelican
Main Object	4	Focus is on the beak and wings of the pelican.
