块世界对话系统中的历史感知问答

History-Aware Question Answering in a Blocks World Dialogue System

University of Rochester(罗切斯特大学)

摘要:

基于对话的空间推理系统必须保持对世界历史状态的记忆。除了传达对话代理在精神上存在并参与任务之外,参考历史状态对于实现协作规划可能是至关重要的(例如,用于计划返回到先前状态或诊断过去的失误)。在本文中,我们将探讨多模态口语对话系统中的空间记忆问题,该系统能够在物理块世界设置中回答有关交互历史的问题。这项工作建立在一个完整的空间问答管道组成的视觉系统,语音输入和输出的动画化身,一个对话系统,强大的解释空间查询,和一个约束求解器,得出答案的基础上3-D空间建模。这项工作的贡献包括一个象征性的对话背景下,登记有关话语历史和世界变化的知识,以及一个自然语言理解模块能够解释自由形式的历史问题和查询对话背景,形成一个答案。

英文摘要:

It is essential for dialogue-based spatial reasoning systems to maintain memory of historical states of the world. In addition to conveying that the dialogue agent is mentally present and engaged with the task, referring to historical states may be crucial for enabling collaborative planning (e.g., for planning to return to a previous state, or diagnosing a past misstep). In this paper, we approach the problem of spatial memory in a multi-modal spoken dialogue system capable of answering questions about interaction history in a physical blocks world setting. This work builds upon a full spatial question-answering pipeline consisting of a vision system, speech input and output mediated by an animated avatar, a dialogue system that robustly interprets spatial queries, and a constraint solver that derives answers based on 3-D spatial modelling. The contributions of this work include a symbolic dialogue context registering knowledge about discourse history and changes in the world, as well as a natural language understanding module capable of interpreting free-form historical questions and querying the dialogue context to form an answer.
