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 is fully on the main object bison.
Main Object	5	The red region in the highlighted visual attributes focuses on the bison.
Main Object	2	I selected 2/5 because the red area covers the bison but it is very inaccurate and also covers the background
Main Object	4	The main object is bison whose most part got focus.
Main Object	1	Highlighted visual attributes is on the bison and surrounding area. cannot focus only on bison but focus big area surrounding it making it difficult to pinpoint


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