What are the characteristics of Labelese?

[Mark Knowles]

I am inclined to the view that there is an overestimate of the useful of TTR in this thread. As already stated it would be expected on the face of it that there would be a higher proportion of unique and less common words amongst labels than amongst sentence text, so the TTR figure definitely has some use. However the TTR figure is a very blunt tool to tell us anything about labels, but we shouldn't be too reliant on this figure.
