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	Highlighted area is focused on the legs and supports of the water tower.
Main Object	4	The red region in the highlighted visual attributes focuses on the part of a water tower.
Main Object	4	Focus is on the base of the water tower.
Main Object	5	The focus is highlighting the structure and ladder
Main Object	5	I am positive that the highlighted area is part of the water tower structure which supports the actual water tower which is a part of the water tower so therefore it is part of the main object


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