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 on the laces of running shoe
Main Object	5	Focus is on the front side of the running shoe from top view.
Main Object	4	The main obect is running shoe whose some part got focus.
Main Object	4	Images 1, 2 and 5 have red regions focusing on the main object (running shoes) only. images 3 and 4 have a lot of focus on the background, but i still think the main focus is on parts of the shoe. there are no other objects shown in any of the pictures.
Main Object	5	The focus of the red region in the highlighted visual attributes is on running shoe.
