A Hierarchical N-Gram Framework for Zero-Shot Link Prediction. (arXiv:2204.10293v5 [cs.CL] UPDATED)

Due to the incompleteness of knowledge graphs (KGs), zero-shot link
prediction (ZSLP) which aims to predict unobserved relations in KGs has
attracted recent interest from researchers. A common solution is to use textual
features of relations (e.g., surface name or textual descriptions) as auxiliary
information to bridge the gap between seen and unseen relations. Current
approaches learn an embedding for each word token in the text. These methods
lack robustness as they suffer from the out-of-vocabulary (OOV) problem.
Meanwhile, models …
