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	The focus of the red region in the highlighted visual attributes is on the top of the light house.
Main Object	4	Focus is on the last flower of the lighthouse.
Main Object	5	Focus is on the tower of the light house
Main Object	4	Focus is on the structure of lighthouse
Main Object	5	The red region is focusing on the middle of the main object (lighthouse) in all 5 pictures. there is no overlap in between a red region and another object, or the background, on any of the 5 images.


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