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	Focus is on part of the snake
Main Object	4	The red color doesn't depict the background because it is highlighted in the body of the snake. so i chose the option
Main Object	5	All the images are mainly focused on main object's body parts.
Main Object	4	Focus is on various parts of snake body
Main Object	2	Focus is on the outside scales of the snake.


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