Position Bias Correction is Insufficient for One-Pass Attention Sorting

Qiong Tang, Xiangkun Hu, Xiangyang Liu +2

Long-context language models suffer from position bias, where information in middle positions is underutilized. Attention Sorting addresses this by iteratively reordering documents…

Can Language Models Learn to Skip Steps?

Tengxiao Liu, Qipeng Guo, Xiangkun Hu +4

Trained on vast corpora of human language, language models demonstrate emergent human-like reasoning abilities. Yet they are still far from true intelligence, which opens up intrig…

Synergetic Event Understanding: A Collaborative Approach to Cross-Document Event Coreference Resolution with Large Language Models

Qingkai Min, Qipeng Guo, Xiangkun Hu +3

Cross-document event coreference resolution (CDECR) involves clustering event mentions across multiple documents that refer to the same real-world events. Existing approaches utili…

Plan, Verify and Switch: Integrated Reasoning with Diverse X-of-Thoughts

Tengxiao Liu, Qipeng Guo, Yuqing Yang +4

As large language models (LLMs) have shown effectiveness with different prompting methods, such as Chain of Thought, Program of Thought, we find that these methods have formed a gr…

An AMR-based Link Prediction Approach for Document-level Event Argument Extraction

Yuqing Yang, Qipeng Guo, Xiangkun Hu +3

Recent works have introduced Abstract Meaning Representation (AMR) for Document-level Event Argument Extraction (Doc-level EAE), since AMR provides a useful interpretation of compl…

Exploiting Abstract Meaning Representation for Open-Domain Question Answering

Cunxiang Wang, Zhikun Xu, Qipeng Guo +4

The Open-Domain Question Answering (ODQA) task involves retrieving and subsequently generating answers from fine-grained relevant passages within a database. Current systems levera…

Evaluating Open-QA Evaluation

Cunxiang Wang, Sirui Cheng, Qipeng Guo +7

This study focuses on the evaluation of the Open Question Answering (Open-QA) task, which can directly estimate the factuality of large language models (LLMs). Current automatic ev…
