reproducible and involves automatic computations. It has thus been
applied on a wide range of systems. It was adopted as the evaluation
framework for the DARPA Communicator project and applied to the
official 2000 and 2001 evaluation experiments [78]. However, exper-
iments on different SDSs reached different conclusions. PARADISE
developers themselves found contradicting results and reported that
time duration was weakly correlated with user satisfaction in [79]
while [80] reports that dialogue duration, task success and ASR per-
formance were good predictors of user’s satisfaction. ...
