The consistency of a response to a given post at semantic-level and
emotional-level is essential for a dialogue system to deliver human-like
interactions. However, this challenge is not well addressed in the literature,
since most of the approaches neglect the emotional information conveyed by a
post while generating responses. This article addresses this problem by
proposing a unifed end-to-end neural architecture, which is capable of
simultaneously encoding the semantics and the emotions in a post and leverage
target information for generating more intelligent responses with appropriately
expressed emotions. Extensive experiments on real-world data demonstrate that
the proposed method outperforms the state-of-the-art methods in terms of both
content coherence and emotion appropriateness.

本研究针对对话系统在生成人类化交互时响应的语义级别和情感级别一致性不足的问题，提出了一种统一的端到端神经架构，它能够同时编码一个帖子的语义和情感信息，并利用目标信息生成更智能、情感表达适当的响应。实验表明，这种方法在内容连贯性和情感恰当性方面优于现有技术。
