Question answering over temporal knowledge graphs (TKGQA) has recently found increasing interest. TKGQA requires temporal reasoning techniques to extract the rele- vant information from temporal knowledge bases. The only existing TKGQA dataset, i.e., C RON Q UESTIONS , consists of temporal questions based on the facts from a fixed time period, where a temporal knowledge graph (TKG) span- ning the same period can be fully used for answer infer-ence, allowing the TKGQA models to use even the fu…

Few-Shot Inductive Learning on Temporal Knowledge Graphs using Concept-Aware Information

This work proposes a few-shot out-of-graph (OOG) link prediction task for TKGs, where the missing entities from the links concerning unseen entities are predicted by employing a meta-learning framework and utilizing the meta-information provided by only few edges associated with each unseen entity.
