Recall, Retrieve and Reason: Towards Better In-Context Relation Extraction

no code implementations27 Apr 2024 Guozheng Li, Peng Wang, Wenjun Ke, Yikai Guo, Ke Ji, Ziyu Shang, Jiajun Liu, Zijie Xu

On the one hand, retrieving good demonstrations is a non-trivial process in RE, which easily results in low relevance regarding entities and relations.

Attention Guidance Mechanism for Handwritten Mathematical Expression Recognition

no code implementations4 Mar 2024 Yutian Liu, Wenjun Ke, Jianguo Wei

Handwritten mathematical expression recognition (HMER) is challenging in image-to-text tasks due to the complex layouts of mathematical expressions and suffers from problems including over-parsing and under-parsing.

Unlocking Instructive In-Context Learning with Tabular Prompting for Relational Triple Extraction

no code implementations21 Feb 2024 Guozheng Li, Wenjun Ke, Peng Wang, Zijie Xu, Ke Ji, Jiajun Liu, Ziyu Shang, Qiqing Luo

The in-context learning (ICL) for relational triple extraction (RTE) has achieved promising performance, but still encounters two key challenges: (1) how to design effective prompts and (2) how to select proper demonstrations.

Revisiting Large Language Models as Zero-shot Relation Extractors

no code implementations8 Oct 2023 Guozheng Li, Peng Wang, Wenjun Ke

On the one hand, we analyze the drawbacks of existing RE prompts and attempt to incorporate recent prompt techniques such as chain-of-thought (CoT) to improve zero-shot RE.
