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	Because the focus of the red color was at least somewhat on the main object in the highlighted visual attributes.
Main Object	5	The main object is an zebra. the focus of the red region in the highlighted visual attributes is on the zebra's head and body, showing their main parts. because of that, i choose focus is on some part of the main object.
Separate Object	4	First two images have the focus on main object(zebra) but the third image has focus on other objects
Main Object	5	The red region in the highlighted visual attributes focuses on the body of a zebra.
Main Object	3	Red focus is on the zebra.


Votes for core: 4, Votes for spurious: 1. Feature is thus annotated as core for the class.
