“…Neural dialogue generation aims at generating natural-sounding replies automatically to exchange information, e.g., knowledge [7,42,58]. As a core component of both task-oriented and non-taskoriented dialogue systems, neural dialogue generation has received a lot attention in recent years [1,3,36,58]. Among all these approaches, sequence-to-sequence structure neural generation models [6,7,23,24,39,41,44,45] have been proved to be capable in multiple dialogue systems with promising performance.…”
