The ability of a dialog system to express prespecified language style during conversations has a direct, positive impact on its usability and on user satisfaction. We introduce a new prototype-to-style (PS) framework to tackle the challenge of stylistic dialogue generation. The framework uses an Information Retrieval (IR) system and extracts a response prototype from the retrieved response. A stylistic response generator then takes the prototype and the desired language style as model input to obtain a high-quality and stylistic response. To effectively train the proposed model, we propose a new style-aware learning objective as well as a de-noising learning strategy. Results on three benchmark datasets from two languages demonstrate that the proposed approach significantly outperforms existing baselines in both in-domain and cross-domain evaluations

在特殊情况下,摘要应符合特定的文体模式,如法院判决书和学术论文摘要。为此,可以利用原型文档-摘要对来生成更好的摘要。在这个任务中有两个主要的挑战:(1)模型需要从原型中整合学习到的模式,但是(2)应该避免将模式化单词以外的内容(例如不相关的事实)复制到生成的摘要中。为了解决这些问题,我们设计了一个基于原型编辑的摘要生成器(Prototype Editing based Summary Generator,PESG)。PESG首先通过分析原型文档与其摘要之间的相关性来学习摘要模式和原型事实。然后利用原型事实来帮助从输入文档中提取事实。接下来,编辑生成器基于概要模式或提取的事实生成新的概要。最后,为了解决第二个挑战,使用事实检查器来估计输入文档和生成的摘要之间的互信息,为生成器提供附加信号。在大规模真实文本摘要数据集上进行的大量实验表明,PESG在自动度量和人工评估方面都达到了最先进的性能。
