Ahhh, these are retrieved from the 'suggestions' list on picNiche.com and not from the toolbar keywording tool?
This is raw (un-processed) data, which is why the picNiche web functionality isn't really a keywording tool as it's mainly for research (though in theory a more descriptive phrase, and thus a higher rated niche produces a better list of potential keywords).
The toolbar keywording functionality is not only a more accurate list of associative data, but also allows refinement of the query across multiple terms.
I'll blog about this in detail as soon as I have the time

Thanks for the feedback
