There is a small correction with respect to the percentage value given to
the entity. I previously thought that the percentage value with the entity
indicated how sure OpenCalais was on the element being an entity. That turns
out to be incorrect.
Thomas from OpenCalais team mailed me the correction and it goes like this:
"Just a quick note on an email I saw on this list. The % returned by Calais
with an entity is not the certainty of correctness – but something much
cooler. It’s actually the computed relevance of the entity to the document
as a whole. Feed it an article with a bunch of entities mentions and we’ll
attempt to identify the most important entities in the content.
Great for noise level reduction in tagging, etc."
