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
Separate Object	3	Red focus is on the water.
Background	5	The highlighted visual attribute is targeting the water around the bird, not the bird itself. that's why i selected background of the main object..
Background	5	Focus is on water in the background of american coot
Background	4	Focus is on the water surrounding the coot.
Background	5	The main object is an american coot, marsh hen, mud hen, water hen, fulica americana. the focus of the red region on the highlighted visual attributes is on the background of these images, showing something that's not relevant for the visual attributes since the main object is a american coot, a bird. because of that, i choose to focus is on the background of the main object.


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