Knowledge Graph Generation From Text

Melnyk, Igor, Dognin, Pierre, Das, Payel

Understand

In this work we propose a novel end-to-end multi-stage Knowledge Graph (KG) generation system from textual inputs, separating the overall process into two stages.

  • The graph nodes are generated first using pretrained language model, followed by a simple edge construction head, enabling efficient KG extraction from the text.
  • For each stage we consider several architectural choices that can be used depending on the available training resources.
  • We evaluated the model on a recent WebNLG 2020 Challenge dataset, matching the state-of-the-art performance on text-to-RDF generation task, as well as on New York Times (NYT) and a large-scale TekGen datasets, showing strong overall performance, outperforming the existing baselines.
