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	3	Focus is on structure which is a part of obelisk
Main Object	5	Focus is on the center of the obelisk.
Main Object	4	The focus is on the obelisk on every photo, just on different parts of it.
Main Object	4	Focus is on some part of the main object obelisk
Main Object	4	Focus is on the center where scripture is engraved on the obelisk.


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