- C. Rosé, A. Waibel. 1994. Recovering From Parser Failures: A Hybrid Statistical/Symbolic Approach. Abstract: W~ describe an implementation of a hybrid statistical/symbolic approach to repairing parser failures in a speech-to-speech translation system. I We describe a rnodale which takes as input a fragmented parse and reeturas a repaired meaning representation. It negotiates with the speaker about what the complete meaning of the utterance is by generating hypotheses about how to fit. the fragments of the partial parse together into a colwrcnt meaning representation. By drawing upon both statistical and symbolic information, it constrains its rcpair hypotheses to those which are both likely and meaningful. Because it updates its statistical model during use, it improves its performance over time.
