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 main focus is the horned viper, and in these images the main focus is right on the horned viper, which is useful and relevant.
Main Object	4	It is clear from the above heatmaps images the focus is on main object viper.
Main Object	4	Body of the snake is focused here.
Main Object	4	The red region in the highlighted visual attributes focuses on the part of a horned viper.
Main Object	4	Focus is on the body of the viper.


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