tblLVST_AnswerUsed
Table Description:
Identifies the answers used in a particular application. To some degree this is application dependent;
the ASR will generally mark the AnswerID (if there is only one, it is automatically marked as the answer),
but the application will have to make a determination as to which n-Best, semantic result, and semantic
object was chosen as the right answer. The relationships are unfortunately complex. The default rules:
Identifying the Answer used: 1. If there is only one answer, then that answer is always chosen as the
answer used. 2. If there is more than one answer, the application should indicate one. If no indication
is made, then the first answer in the log will be used. Identifying the n-Best used: 1. If there is only
one n-best result for chosen answer, then that n-best result is the n-best used. 2. If there is more than
one n-best answer, the application should indicate one. If no indication is made, than the first n-best
answer for that answer is used. Identifying the Semantic Result used: 1. If there is only one semantic
result, then that semantic result for the n-best and answer is chosen. 2. If there is more than one
semantic result for the n-best and answer, then the application must indicate the semantic
result. If no indication is present, no precise automatic semantic evaluation can be accomplished. Identifying
Semantic Object used: 1. The choice of which semantic object is used requires the
application to indicate which object was correct. 2. If this field is -1, and the semantic result is not -1
or 0, then the entire semantic result is assumed to be correct.
