Language understanding component for Chinese dialogue system

In this paper we present the design and the implement of the language understanding component of a Chinese spoken language dialogue system EasyNav. In pursuing the coherence with the goal of understanding, we design the structure of system with speech decoding and language understanding integrated closely. Thus the language understanding component need to be restrictive besides portable. Actually we implement a general syntactic parser and domain-specific semantic parser for the purpose. The grammar rules written for understanding are suitable for spoken language. The feature of spoken language also exists throughout the system.
