Building systems that can communicate with humans is a core problem in
Artificial Intelligence. This work proposes a novel neural network architecture
for response selection in an end-to-end multi-turn conversational dialogue
setting. The architecture applies context level attention and incorporates
additional external knowledge provided by descriptions of domain-specific
words. It uses a bi-directional Gated Recurrent Unit (GRU) for encoding context
and responses and learns to attend over the context words given the latent
response representation and vice versa.In addition, it incorporates external
domain specific information using another GRU for encoding the domain keyword
descriptions. This allows better representation of domain-specific keywords in
responses and hence improves the overall performance. Experimental results show
that our model outperforms all other state-of-the-art methods for response
selection in multi-turn conversations.

本文提出了一种新颖的神经网络架构，用于多轮对话场景下的响应选择，它应用了上下文级别的注意力和领域特定单词描述提供的额外外部知识。该架构使用双向门控循环单元进行编码，并学习在给定潜在响应表示的上下文单词之间进行关注，同时还使用另一个 GRU 来编码领域关键词描述，从而提高了相应中领域特定关键词的表示，实验结果表明，相对于所有其他最先进的方法，我们的模型在多轮对话中具有更好的响应选择性能。
