Strategies for Mixed-Initiative Conversation Management using Question-Answer Pairs
نویسندگان
چکیده
One of the biggest bottlenecks for conversational systems is large-scale provision of suitable content. In this paper, we present the use of content mined from online question-and-answer forums to automatically construct system utterances. Although this content is mined in the form of question-answer pairs, our system is able to use it to formulate utterances that drive a conversation, not just for answering user questions as has been done in previous work. We use a collection of strategies that specify how and when the question-answer pairs can be used and augmented with a small number of generic hand-crafted text snippets to generate natural and coherent system utterances. Our experiments involving 11 human participants demonstrated that this approach can indeed produce relatively natural and coherent interaction.

We envision that next-generation spoken dialogue systems will be mixed-initiative. However, it is unclear how exactly a mixed-initiative strategy should be designed; under what circumstances should the system take the initiative, and under what circumstances should it let the user do so. The initiative strategies used in human-human conversation are a good starting point, because they are natur...
