Before revision:  However, there are still two issues need to consider: (1) How to effectively represent the knowledge bases and incorporate it into dialogue system. (2) How to efficiently reason the knowledge bases given queries. To solve these issues , we design a novel Transformer-based Dynamic Memory Network (DMN) with a novel Memory Mask scheme , which can dynamically generate the context-aware knowledge base representations , and reason the knowledge bases simultaneously .
