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	4	Focus is on some area of spike
Main Object	5	All the images are mainly focused on main object's body parts.
Main Object	5	The focus of the red region in the highlighted visual attributes is on capitulum.
Main Object	5	All the images have red regions focusing on the kernels of the corn, which is a part of the main object (ear of the corn). there are no red region areas overlapping with the background, or any other object in any of the pictures.
Main Object	4	Focus on top of spike


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