Re: Another comment about confidence value.

Hi Charles,

I would suggest that confidence is interpreted as it is defined in
statistics; i.e. as a probability which is a real number from and
inclusive 0 and to and inclusive 1. 

If some applications want to map this basic definition to percentage or
some other scheme, then they can define their own mappings, e.g. "low is
confidence less than 0.3, medium is confidence between 0.3 and 0.7 and
high is confidence greater than 0.7". or "Confidence percentage is
probability times 100". Those implementors that need such mappings can
provide customized RDF/OWL schema and constraints to give a unique
interpretation for their specific applications. 

Using the probability is a generally accepted way of representing
confidence values in most areas of science. Other representations can be
derived from this.
