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 red regions on all 5 images are focusing on a part of the main object. there is no overlap in between a red region and an object other than the main one. there is some background highlited in red on images 2, 3, 4 and 5, but the focus is clearly always in some part of the main object.
Main Object	4	The red region mainly focuses on the predicted object but slightly spreads to the background and doesn't cover it fully.
