15. A non-transitory computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising: identifying, in a domain-independent manner, a dialog act for an independent clause of a speech recognizer output; identifying, in a domain-dependent manner, an object within the independent clause; and recursively generating, for each sub-independent clause within the independent clause, a semantic representation using the dialog act and the object of the independent clause.
