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
Background	4	Images 2, 3, 4 and 5 have red region focusing on the background. image 1 has the red region focusing on the main object, but the majority of the images fits the first option of q1, so i went with it.
Background	4	Focus is on the greenery surrounding the coucal.
Background	5	Most of the images are mainly focused on background only.
Background	3	Highlighted areas are focused on the background behind the bird, but not the coucal itself.
Background	3	All the birds red higlighted regions are good


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