Enhancing Numerical Reasoning with the Guidance of Reliable Reasoning Processes

no code implementations16 Feb 2024 Dingzirui Wang, Longxu Dou, Xuanliang Zhang, Qingfu Zhu, Wanxiang Che

Numerical reasoning is an essential ability for NLP systems to handle numeric information.

Multi-Hop Table Retrieval for Open-Domain Text-to-SQL

no code implementations16 Feb 2024 Xuanliang Zhang, Dingzirui Wang, Longxu Dou, Qingfu Zhu, Wanxiang Che

To reduce the effect of the similar irrelevant entity, our method focuses on unretrieved entities at each hop and considers the low-ranked tables by beam search.

A Survey of Table Reasoning with Large Language Models

1 code implementation13 Feb 2024 Xuanliang Zhang, Dingzirui Wang, Longxu Dou, Qingfu Zhu, Wanxiang Che

In this paper, we analyze the mainstream techniques used to improve table reasoning performance in the LLM era, and the advantages of LLMs compared to pre-LLMs for solving table reasoning.

Exploring Equation as a Better Intermediate Meaning Representation for Numerical Reasoning

1 code implementation21 Aug 2023 Dingzirui Wang, Longxu Dou, Wenbin Zhang, Junyu Zeng, Wanxiang Che

So in this paper, we try to use equations as IMRs to solve the numerical reasoning task by addressing two problems: (1) Theoretically, how to prove that the equation is an IMR with higher generation accuracy than programs; (2) Empirically, how to improve the generation accuracy of equations with LLMs.
