Arborist

Arborist accurately expands large-scale taxonomies with edge semantics that are heterogeneous and unobserved.

Arborist learns global latent representations of the edge semantics with local taxonomic-role embeddings of the nodes.

Arborist guarantees easy human verification by minimizing the network distance between predicted and actual taxonomy parents.
