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	All the images are fully focused on main object's body parts.
Main Object	5	Focus is on the snake's head.
Main Object	4	Focus on the eyes and tail of snake
Main Object	5	Focus is clearly on the snake
Main Object	3	Red focus is on the body of snake.


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