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 focus is on some part of the main object.
Main Object	5	The main object is an jack-o'-lantern. the focus of the red region in the highlighted visual attributes is on the lantern carved from a pumpkin, showing its main parts. because of that, i choose focus is on some part of the main object.
Main Object	3	The red region in the highlighted visual attributes focuses on the part of a jack-o'-lantern.
Main Object	3	The main object is jack-o'-lantern whose some part got focus.
