function Rlink( modelname : String, nqs : NetricsQuery[], use_threshold : bool ) : NetricsQuery |
Parameters
- modelname
- the name of the decision engine model to use
- nqs
- list of NetricsQuery objects that are the sub expressions for this RLINK expression. The number of querylets must be the same as the number of features in the model.
- use_threshold
- if true the threshold value stored in the model is used as the absolute cut off score.
Remarks
The Rlink query uses a TIBCO Patterns Learn Model to intelligently combine querylet scores to produce a single match score. Its use is similar to that of the AND score combiner.
The named model must have been trained with the same set or querylets as passed to the RLINK combiner.
This call allows the use threshold flag to be set. A Patterns Learn Model file may have a cutoff threshold score stored in it. If the use threshold flag is set this score is used as the absolute cutoff score for the query. No records with scores below this value are returned. This supercedes any cutoff specified in the search options. If the named Patterns Learn Model does not contain a threshold score this flag is quietly ignored.
