Chinese spoken language understanding across domain

A robust parsing model for spontaneous Chinese based on semantic constituent spotting and concept assembling model (SCAM) had been successfully developed in our “LOADSTAR”dialog system[1]. It is a travel information accessing system and the SCAM is rule based. Considering the domain portability, a statistical model for spoken language understanding is adopted. The statistical spoken language understanding model is developed in the domain of hotel reservation. Then the statistical model was ported to the domain of travel information accessing within four weeks.
