Improved Concept Embeddings for Learning Prerequisite Chains: Methods

  • Poincaré embeddings (Nickel and Kiela, 2017) is a method that better fit for data with latent hierarchies than other embedding models using the Euclidean vector space.
  • Dhingra et al. (2018) introduced a method to obtain Poincaré word embeddings from natural language text.
  • This paper combines the two methods above to obtain prerequisite relations between concepts from two datasets in the domain of Natural Language Processing.
