Two-stage Generative Question Answering on Temporal Knowledge Graph Using Large Language Models

no code implementations26 Feb 2024 Yifu Gao, Linbo Qiao, Zhigang Kan, Zhihua Wen, Yongquan He, Dongsheng Li

Temporal knowledge graph question answering (TKGQA) poses a significant challenge task, due to the temporal constraints hidden in questions and the answers sought from dynamic structured knowledge.
