From Question Answering to Spoken Dialogue : Towards an Information Search Assistant for Interactive Multimodal Information Extraction

摘要: This paper gives an overview of issues related to extending simple question answering (QA) with dialogue capabilities, when designing a multimodal interactive information extraction system for large, though restricted, domain. We present the way in which these are approached IMIX program. The demonstrator system, under development this program, may be considered most difficult case QA, non-factoid questions large domain, and accepting speech input as well. describe our approach addition capabilities system. will look at QA from perspective HCI perspective, consider consequences choice interaction metaphor, `information search assistant'.
