We present a novel spoken dialogue system which uses the up-to-date information on the web. It is based on information extraction which is defined by the predicate-argument (P-A) structure and realized by shallow parsing. Based on the information structure, the dialogue system can perform question answering and also proactive information presentation using the dialogue context and a topic model.
