Abstract
... This paper addresses the issue of the robustness of the Data Oriented Parsing (DOP) model within a Dutch speech-based dialogue system. It presents an extension of the DOP1 model into a head-driven variant, which allows for Markovian generation of parse-trees. It is shown empirically that the new variant improves over the original DOP1 model on two tasks: the formal understanding of speech utterances, and the extraction of semantic-concepts from "word-lattices" output by a speech-recognizer.
