one or more computer-readable media coupled to one or more of the processing unit(s), the one or more computer readable media having thereon one or more modules of computer-executable instructions to configure a computer to perform operations comprising:
building a multi-domain classifier model configured to jointly model domain, intent, and a sequence of one or more slot values for a natural-language sequence of words, the model comprising a recurrent neural network (RNN) that operates on an input sequence comprising (n+1) input elements to generate an output sequence comprising (n+1) output elements each uniquely associated with a corresponding one of the input elements, the input sequence comprising a sequence of n tokens representing the words of the natural-language sequence and the output sequence comprising a sequence of n slot tags associated with respective tokens representing the words of the natural-language sequence, an (n+1)-th element of the input sequence being an end-of-sequence token and an associated (n+1)-th element of the output sequence being a concatenation of domain and intent tags.
