摘要:

神经网络模型能够生成非常自然的对话交互。尽管如此,这些模型还没有证明它们可以以事实信息或实体为基础的意见的形式纳入内容,使它们能够在更多面向任务的会话应用程序中服务。本文提出了一种新颖的、完全数据驱动的、以知识为基础的神经会话模型,旨在产生更满意的响应,而无需填充槽。我们推广了广泛使用的Seq2Seq方法,通过对会话历史和外部“事实”的条件反应,使该模型在开放域环境中具有通用性和适用性。我们的方法在竞争性Seq2Seq基线上产生了显着的改进。人类法官发现我们的输出信息量更大。

英文摘要:

Neural network models are capable of generating extremely natural sounding conversational interactions. Nevertheless, these models have yet to demonstrate that they can incorporate content in the form of factual information or entity-grounded opinion that would enable them to serve in more task-oriented conversational applications. This paper presents a novel, fully data-driven, and knowledge-grounded neural conversation model aimed at producing more contentful responses without slot filling. We generalize the widely-used Seq2Seq approach by conditioning responses on both conversation history and external "facts", allowing the model to be versatile and applicable in an open-domain setting. Our approach yields significant improvements over a competitive Seq2Seq baseline. Human judges found that our outputs are significantly more informative.
