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
Separate Object	5	Focus is highlighting the screens around the image
Main Object	2	Focus is on part of a yurt
Main Object	5	Images 1, 3, 4 and 5 have the red region focusing on the main object. image 2 does not have the main object, and the red region is focusing on a pattern similar to the one characteristic of the main object structure.
Separate Object	5	It appears to be focussing on any form of mesh such as fences rather than the structure of a yurt.
Main Object	4	Focus is on yurt structure


Votes for core: 3, Votes for spurious: 2. Feature is thus annotated as core for the class.
