论文摘要
有说服力的战略认可任务要求该系统根据对话识别说服者的采用策略。但是，以前的方法主要关注上下文信息，关于结合心理反馈，即说服的情绪以预测策略知之甚少。在本文中，我们提出了一个跨渠道反馈记忆网络（CFO-NET），以利用情感反馈来迭代地衡量策略的潜在好处，并将其纳入上下文感知的对话信息中。具体而言，CFO-NET设计一个反馈内存模块，包括策略池和反馈池，以获得情感感知的策略表示。该策略池旨在存储历史策略，反馈池是根据反馈情感信息获得更新的策略权重。此外，开发了跨通道融合预测指标，以在情绪感知的策略表示与情境意识的对话信息之间进行相互互动，以识别战略。 \ textsc {celpuasionforgood}的实验结果证实，提出的模型CFO-NET可有效地将M-F1的性能从61.74提高到65.41。
Persuasive strategy recognition task requires the system to recognize the adopted strategy of the persuader according to the conversation. However, previous methods mainly focus on the contextual information, little is known about incorporating the psychological feedback, i.e. emotion of the persuadee, to predict the strategy. In this paper, we propose a Cross-channel Feedback memOry Network (CFO-Net) to leverage the emotional feedback to iteratively measure the potential benefits of strategies and incorporate them into the contextual-aware dialogue information. Specifically, CFO-Net designs a feedback memory module, including strategy pool and feedback pool, to obtain emotion-aware strategy representation. The strategy pool aims to store historical strategies and the feedback pool is to obtain updated strategy weight based on feedback emotional information. Furthermore, a cross-channel fusion predictor is developed to make a mutual interaction between the emotion-aware strategy representation and the contextual-aware dialogue information for strategy recognition. Experimental results on \textsc{PersuasionForGood} confirm that the proposed model CFO-Net is effective to improve the performance on M-F1 from 61.74 to 65.41.
