论文摘要

情感支持对话(ESCONV)旨在通过支持性策略和反应来减少寻求帮助者的情感困扰。支持者必须在Esconv中选择一个寻求帮助者的反馈(例如,在对话旋转期间的情绪变化等)选择适当的策略。但是,以前的方法主要集中于对话历史记录,以选择策略并忽略寻求帮助者的反馈,从而导致错误和用户 - Irrelevant策略预测。此外,这些方法仅对上下文到策略的流程进行建模,并更少注意策略至上的流动,该流程可以集中于与策略相关的上下文,以产生策略构成响应。在本文中,我们提出了一个反馈意见的双重控制网络(FADO),以制定策略时间表并产生支持性响应。 FADO中的核心模块由双级反馈策略选择器和双控制读取器组成。具体而言,双级反馈策略选择器利用转向级别和对话级别的反馈来鼓励或惩罚策略。双控制读取器构建了新型策略至上的流程,以产生策略构成响应。此外,战略词典旨在丰富战略的语义信息并提高策略构成响应的质量。 Esconv的实验结果表明,拟议中的Fado在策略选择和响应生成方面都取得了最新的表现。我们的代码可在https://github.com/thedatabbler/fado上找到。

Emotional Support Conversation (ESConv) aims to reduce help-seekers'emotional distress with the supportive strategy and response. It is essential for the supporter to select an appropriate strategy with the feedback of the help-seeker (e.g., emotion change during dialog turns, etc) in ESConv. However, previous methods mainly focus on the dialog history to select the strategy and ignore the help-seeker's feedback, leading to the wrong and user-irrelevant strategy prediction. In addition, these approaches only model the context-to-strategy flow and pay less attention to the strategy-to-context flow that can focus on the strategy-related context for generating the strategy-constrain response. In this paper, we propose a Feedback-Aware Double COntrolling Network (FADO) to make a strategy schedule and generate the supportive response. The core module in FADO consists of a dual-level feedback strategy selector and a double control reader. Specifically, the dual-level feedback strategy selector leverages the turn-level and conversation-level feedback to encourage or penalize strategies. The double control reader constructs the novel strategy-to-context flow for generating the strategy-constrain response. Furthermore, a strategy dictionary is designed to enrich the semantic information of the strategy and improve the quality of strategy-constrain response. Experimental results on ESConv show that the proposed FADO has achieved the state-of-the-art performance in terms of both strategy selection and response generation.
