In this paper we give an overview of the NLP and dialog component in the Waxholm spoken dialog system. We will discuss how the dialog and the natural language component are modeled from a generic and a domain-specific point of view. Dialog management based on grammar rules and lexical semantic features is implemented in our parser. The notation to describe the syntactic rules has been expanded to cover some of our special needs to model the dialog. The parser is running with two different time scales corresponding to the words in each utterance and to the turns in the dialog. Topic selection is accomplished based on probabilities calculated from user initiatives. Results from parser performance and topic prediction are included.
