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	2	Focus on laptop
Main Object	4	The red region in the highlighted visual attributes focuses on the part of the modem.
Separate Object	5	Not all images are that of modem.
Main Object	3	The focus is on the body of the modem or electronic device.
Main Object	5	The red regions are focused on the top or cover of the modems and nothing else.


Votes for core: 4, Votes for spurious: 1. Feature is thus annotated as core for the class.
