ItD: Large Language Models Can Teach Themselves Induction through Deduction

no code implementations9 Mar 2024 Wangtao Sun, Haotian Xu, Xuanqing Yu, Pei Chen, Shizhu He, Jun Zhao, Kang Liu

Although Large Language Models (LLMs) are showing impressive performance on a wide range of Natural Language Processing tasks, researchers have found that they still have limited ability to conduct induction.

ZeroKBC: A Comprehensive Benchmark for Zero-Shot Knowledge Base Completion

1 code implementation6 Dec 2022 Pei Chen, Wenlin Yao, Hongming Zhang, Xiaoman Pan, Dian Yu, Dong Yu, Jianshu Chen

However, there has been limited research on the zero-shot KBC settings, where we need to deal with unseen entities and relations that emerge in a constantly growing knowledge base.
