We describe a parser for robust and flexible inter- pretation of user utterances in a multi-modal sys- tem for web search in newspaper databases. Users can speak or type, and they can navigate and follow links using mouse clicks. Spoken or written queries may combine search expressions with browser com- mands and search space restrictions. In interpreting input queries, the system has to be fault-tolerant to account for spontanous speech phenomena as well as typing or speech recognition errors which often distort the meaning of the utterance and are difficult to detect and correct. Our parser integrates shallow parsing techniques with knowledge-based text re- trieval to allow for robust processing and coordina- tion of input modes. Parsing relies on a two-layered approach: typical meta-exp...
