Toward Subgraph-Guided Knowledge Graph Question Generation with Graph Neural Networks

Chen, Yu, Wu, Lingfei, Zaki, Mohammed J.

Understand

Knowledge graph (KG) question generation (QG) aims to generate natural language questions from KGs and target answers.

  • Previous works mostly focus on a simple setting which is to generate questions from a single KG triple.
  • In this work, we focus on a more realistic setting where we aim to generate questions from a KG subgraph and target answers.
  • In addition, most of previous works built on either RNN-based or Transformer based models to encode a linearized KG sugraph, which totally discards the explicit structure information of a KG subgraph.
