I would be also extremely interested in an answer to this. Thanks for
asking, Stefano.
What's the best way to calculate "Spotlight's detection confidence" = a
single number?
Cheers,
Radim

Předmět: [Dbp-spotlight-users] How is the confidence value calculated?
"
Hi,
I am new to this list, I came here from the github Spotlight page about
support and feedback. Questions related to what I am asking have popped up a
couple of times in this list as far as I can see, but the answers do not
provide what I am looking for.
I am using the statistical back-end, and I am basically trying to
reconstruct the confidence value of the entities extracted.
I have extracted entities from tweets and as a first experiment I did not
asked for any threshold confidence. Now I would like to calculate the
confidence of each results to see how filtering based on that influences the
quality of some other process I am doing with the entities.
I am now using the formula:
(1 - .5 * percentageofsecondrank) * similarityscore
Based on the fact that confidence increases with similarity score, but
decreases if the second candidate is also similar.
Is this comparable to what Spotlight uses in http://spotlight.dbpedia.org/
rest/annotate(http://spotlight.dbpedia.org/rest/annotate)? Or else what is
the formula? Does support play a role?
Thanks,
Stefano
