Description

The "confidence-level" is intended to make it easier for clients to
decide how to process Enhancements. It would not use a numerical range
but four distinct values:

• confident: Meaning that a match is very likely - indicating that
  those annotations typically can be accepted automatically (e.g. If the
  EntityLinking engine finds a single Entity that exactly matches the
  text selected by an text annotation)
• ambiguous: Meaning that there are several possibilities but is is
  still likely that one of them match (e.g. Paris, Paris (Texas))
• suggestion: Meaning that the match is not completely certain, but
  there are not several options (e.g. Germans -> Germany)
• uncertain: Meaning that Entities do match, but the probability of a
  match is rather speculative (e.g. John -> Elton John)

IMHO using this classification would fit a lot of engines much better
as the numeric "fise:confidence" property as it does not rise the
expectation in users that confidence values are on a rational scale
(e.g. a Enhancement with a confidence of "0.8" is not two times as
likely as one with "0.4").
