论文摘要
实现混合发射的人类 - 计算机参考沟通的先前方法采用了信息国家或协作解决问题的方法。在本文中，我们主张一种新方法，灵感来自基于连贯的话语模型，例如sdrt \ cite {asher-lascarides：2003a}，其中讲话附加到不断发展的话语结构以及相关的扬声器承诺的相关知识图中，作为对现实推理和对话策略的接口。作为实施该方法的第一步，我们在参考通信领域中描述了一个简单的对话系统，该对话系统在跨话语中积累约束，使用学习的概率模型来解释它们，并使用强化学习计划澄清。
Prior approaches to realizing mixed-initiative human--computer referential communication have adopted information-state or collaborative problem-solving approaches. In this paper, we argue for a new approach, inspired by coherence-based models of discourse such as SDRT \cite{asher-lascarides:2003a}, in which utterances attach to an evolving discourse structure and the associated knowledge graph of speaker commitments serves as an interface to real-world reasoning and conversational strategy. As first steps towards implementing the approach, we describe a simple dialogue system in a referential communication domain that accumulates constraints across discourse, interprets them using a learned probabilistic model, and plans clarification using reinforcement learning.
