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	The red region completely focuses on the predicted object's snout but doesn't cover it fully.
Main Object	4	Highlighted in lion nose and mouth
Main Object	4	Above images focusing on some part of the main object.
Main Object	3	Red focus is on the mouth of lion.
Main Object	4	Focus is on the nose of the lion.


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