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 on the faucet and drain, but not the washbasin itself.
Main Object	5	Focus is on wash-hand basin
Main Object	3	Red focus is on wash basins.
Main Object	4	The main object is washbasin whose some part got focus.
Main Object	4	Focus is on the drain outlet in the washbasin.


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