Returns a relative measure of the certainty as to the correctness of the semantic parsing that returned the current instance of SemanticValue.

Property Value
Type: System..::..SingleReturns a float that is a relative measure of the certainty as to the correctness of the semantic parsing that returned the current instance of SemanticValue.
Remarks
The SemanticValue..::..Confidence property, which returns a measure of the correctness of semantic parsing, should not be confused with the RecognizedPhrase..::..Confidence property, which returns a measure of the accuracy of speech recognition.
Examples
The following example is used to recursively traverse and then display information (including confidence) as a TreeNodeCollection, or as the nodes making up the tree structure of the semantics used to recognize a phrase.
