Arbitration of Natural Language Understanding Applications

Abstract:

A natural language understanding (NLU) system includes an arbitrator and a NLU stage. The arbitrator processes a transcription of a query and identifies, from a set of domains, a domain corresponding to the query. Each NLU application corresponds to one or more domains. Based on this identification, the arbitrator generates a match result indicating the domain. The NLU stage includes a plurality of NLU applications, and applies the query to one or more of the NLU applications based on the match result.
