Center node: "automatic transferring between ancient chinese and contemporary chinese"
  Abstract: During the long time of development, Chinese language has evolved a great deal. Native speakers now have difficulty in reading sentences written in ancient Chinese. In this paper, we propose an unsupervised algorithm that constructs sentence-aligned ancient-contemporary pairs out of the abundant passage-aligned corpus. With this method, we build a large parallel corpus. We propose to apply the sequence to sequence model to automatically transfer between ancient and contemporary Chinese sentences. Experiments show that both our alignment and transfer method can produce very good result except for some circumstances that even human translators can make mistakes without background knowledge.

Connected through hyperedge HE-1 (induced by source paper "ancient modern chinese translation with a new large training dataset"):
