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	Focus is on the snake's eye.
Main Object	5	Because the focus of the red color was at least somewhat on the main object, or the snake body and eyes in this particular example
Main Object	3	Body of the snake is highlighted.
Main Object	4	The red region in the highlighted visual attributes focuses on the body part of a garter snake.
Main Object	5	Focus on the eyes of the main object.


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