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	3	Red focus is on the yurt.
Main Object	5	Focus is on door of house
Main Object	4	Focus is on the roof of the yurt.
Main Object	4	The red region mainly focuses on the predicted object but slightly spreads to the background on the second image and doesn't cover it fully.
Main Object	5	All 5 images have red regions focusing on part of the main object. there is some overlap with the background in pictures 1 and 2, but it's not significant. there is no other object than the main one highlited by a red region.


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