摘要:

在端到端对话系统中,对话状态跟踪的目的是根据由语音识别和自然语言理解模块产生的噪声观测序列来准确地估计当前对话状态的紧凑表示。本文介绍了一种新的方法,对话状态跟踪的基础上,机器阅读的一般范式,并提出解决它使用端到端的内存网络,MemN 2N,内存增强的神经网络架构。我们在第二个对话状态跟踪挑战(DSTC-2)数据集上评估了所提出的方法。语料库已被转换的场合,以帧的隐藏状态变量推理作为一个问答任务的基础上从对话中提取的一系列话语。我们表明,建议的跟踪器给出了令人鼓舞的结果。然后,我们建议扩展DSTC-2数据集与特定的推理能力的要求,如计数,列表维护,是非问答和不确定的知识管理。最后,我们提出了令人鼓舞的结果,使用我们提出的基于MemN 2N的跟踪模型。

英文摘要:

In an end-to-end dialog system, the aim of dialog state tracking is to accurately estimate a compact representation of the current dialog status from a sequence of noisy observations produced by the speech recognition and the natural language understanding modules. This paper introduces a novel method of dialog state tracking based on the general paradigm of machine reading and proposes to solve it using an End-to-End Memory Network, MemN2N, a memory-enhanced neural network architecture. We evaluate the proposed approach on the second Dialog State Tracking Challenge (DSTC-2) dataset. The corpus has been converted for the occasion in order to frame the hidden state variable inference as a question-answering task based on a sequence of utterances extracted from a dialog. We show that the proposed tracker gives encouraging results. Then, we propose to extend the DSTC-2 dataset with specific reasoning capabilities requirement like counting, list maintenance, yes-no question answering and indefinite knowledge management. Finally, we present encouraging results using our proposed MemN2N based tracking model.
