<pre>
The relevancy of the ICA (Image Content Annotation) label to the
image. For example, the relevancy of "tower" is likely higher to an image
containing the detected "Eiffel Tower" than to an image containing a
detected distant towering building, even though the confidence that
there is a tower in each image may be the same. Range [0, 1].
