Experiments on two domains of the MultiDoGO dataset reveal challenges of constraint violation detection and sets the stage for future work and improvements. The results from the empirical work present that the new ranking mechanism proposed shall be more practical than the former one in several points. Extensive experiments and analyses on the lightweight models present that our proposed strategies achieve considerably larger scores and substantially enhance the robustness of both intent detection and slot filling.
