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 is on the fish
Main Object	5	Most of the images are mainly focused on main object's body parts.
Main Object	5	The red regions on all 5 images are focusing on parts of the main object. there is some overlap in between a red region and the background on all 5 pictures, but the focus, i've judged, is completely on the tentacles of the jellyfish (part of the main object) when those overlaps occur.
Main Object	5	The main focus is on the jellyfish stingers and the body of the jelly fish which is part of the main object
Main Object	3	Red focus is on the jelly fish.


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