hot_or_not_author_spatial_rationale_annotations.zip is a zip file containing MATLAB annotation data from our experiment on the Hot or Not dataset which we created to test our approach on a subjective task.  This file contains only the annotations that we (the authors) did ourselves.  It does NOT contain the annotation data collected from MTurk.  (The image and rating data for the Hot or Not dataset can be downloaded separately from the "Data" section of our project page.)

It has two directories:
	female_rats/
	male_rats/

female_rats/ and male_rats/ each contain a few hundred .mat files; one for each image we annotated.  The file male_rats/0220.mat (for example) corresponds to the image male/0220.jpg (and text file male/0220.txt) in the image and rating data files.

We can view the annotation for male_rats/0220.mat in MATLAB as follows:
	>> load('male_rats/0220.mat')
	>> annotation

	annotation =

	    polygonsX: {[11x1 double]}
	    polygonsY: {[11x1 double]}

The annotation only contains the XY coordinates of the vertices of the rationale polygon(s) for this image (this particular rationale annotation has a single polygon with 11 vertices).  It does not contain a class label, because we assume the "hot"/"not" labeling given by the hotornot.com raters.
