MTurk Worker Annotations

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	The red region in the highlighted visual attributes focuses on the part of the paper towel.
Main Object	4	It appears to be finding white cylinders rather than just paper towels with particular attention to the open end of a cylinder hence the interest shown in the container of liquid being poured.
Main Object	5	The red is in the middle of the paper towel.
Main Object	3	Focus is on the roll of paper towel.
Separate Object	3	The highlighted visual attributes is correct in the first two images. the remaining three images do not contain paper towels.


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