Abstract :
We present a new approach to natural language understanding (NLU) based on the source-channel paradigm, and apply it to ARPA´s Air Travel Information Service (ATIS) domain. The model uses techniques similar to those used by IBM in statistical machine translation. The parameters are trained using the exact match algorithm; a hierarchy of models is used to facilitate the bootstrapping of more complex models from simpler models
