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	Q1: there is no overlapping in between a red region and the background. there is some overlap in between a red region and objects (ice cream container) different from the main one (ice cream) in all 5 images, but it's not significant. the focus of the red regions are clearly on the main object.
Main Object	4	The red region mainly focuses on the predicted object but ovelaps with the container near it.
Main Object	5	From the heatmaps of the product it is clear that the intensity of red color is high on some part of the main object.
Main Object	5	The focus is on the ice cream which is the main object
Main Object	4	Focus is on features of the object.


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