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	4	The main focus is on the upper portion of the carousel which is part of the main object
Main Object	5	Images are fully focused on main object's body parts.
Main Object	5	The focus on all 5 images is on parts of the main object (the top of the carrousel). there is no overlap in between a red region, and the background, or other object than the main one in any of the five pictures.
Main Object	2	Focus is on the instrument
Main Object	3	Red focus is on the merry-go-round.


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