MURRE: Multi-Hop Table Retrieval with Removal for Open-Domain Text-to-SQL (2025.coling-main)
Copied to clipboard
| Challenge: | Existing multi-hop retrieval of open-domain text-to-SQL tasks is not applicable due to the tendency to retrieve tables similar to those already retrieved but irrelevant to the question. |
| Approach: | They propose a multi-hop table retrieval with removal task to retrieve unretrieved tables from open-domain text-to-SQL databases. |
| Outcome: | The proposed method improves performance 5.7% over the previous state-of-the-art methods on open-domain text-to-SQL datasets. |
DAC: Decomposed Automation Correction for Text-to-SQL (2025.findings-emnlp)

| Challenge: | Existing methods to improve text-to-SQL performance are hard to detect errors in SQL directly. |
| Approach: | They propose to use decomposed correction to improve text-to-SQL performance . they first detect errors based on decompose subtasks, then use it to correct them . |
| Outcome: | The proposed method improves text-to-SQL performance by 1.4% compared with previous methods . |
Enhancing Numerical Reasoning with the Guidance of Reliable Reasoning Processes (2024.acl-long)
Copied to clipboard
| Challenge: | Numerical reasoning is an essential ability for NLP systems to handle numeric information. |
| Approach: | They propose a numerical reasoning method that generates reliable reasoning processes by decomposing the answer formula and aim to train models to generate the process with synthesized data. |
| Outcome: | The proposed method improves on all five datasets with an average improvement of 1.8% compared with baselines and gpt-3.5-turbo. |

Longxu Dou, Yan Gao, Xuqi Liu, Mingyang Pan, Dingzirui Wang, Wanxiang Che, Dechen Zhan, Min-Yen Kan, Jian-Guang Lou
| Challenge: | Existing approaches to text-to-SQL require domain knowledge to parse expert questions into SQL queries. |
| Approach: | They propose a framework to leverage domain knowledge during parsing by building a new benchmark KnowSQL with domain-specific questions. |
| Outcome: | The proposed framework improves the performance of the proposed benchmark by 28.2%. |
Sailor: Open Language Models for South-East Asia (2024.emnlp-demo)
Copied to clipboard
| Challenge: | Large language models (LLMs) rely on English data for training, but are often not comparable across other languages. |
| Approach: | They propose to develop a family of open language models for SEA languages . they use BPE dropout, aggressive data cleaning and deduplication to improve model robustness . |
| Outcome: | The proposed models perform well across four benchmarks, including commonsense reasoning, question answering, reading comprehension and examination. |

| Challenge: | Existing data on MBTI personality detection are based on self-reported labels and fail to capture the full range of population personality traits. |
| Approach: | They construct a manually annotated MBTI personality detection dataset with soft labels under the guidance of psychologists and use them to identify the task. |
| Outcome: | The MBTIBench is the first manually annotated MBti personality detection dataset with soft labels under the guidance of psychologists. |
SCITAT: A Question Answering Benchmark for Scientific Tables and Text Covering Diverse Reasoning Types (2025.findings-acl)

Xuanliang Zhang, Dingzirui Wang, Baoxin Wang, Longxu Dou, Xinyuan Lu, Keyan Xu, Dayong Wu, Qingfu Zhu
| Challenge: | Existing scientific question answering datasets lack diverse reasoning types and neglect relevance between tables and text. |
| Approach: | They propose a scientific question answering benchmark for scientific tables and text with diverse reasoning types (SCITAT) to address these challenges, they propose QA benchmark which incorporates tables and texts to ensure that the questions encompass both tables and textes. |
| Outcome: | The proposed benchmark improves by 4.1% over baselines on SCITAT. |
Data2Text Studio: Automated Text Generation from Structured Data (D18-2)
Copied to clipboard
| Challenge: | Data2Text Studio is a platform for automated text generation from structured data. |
| Approach: | They conduct experiments on RotoWire datasets for template extraction and text generation . they find that the Semi-HMMs model improves interactivity and interpretability . |
| Outcome: | The proposed model improves on template extraction and text generation tasks on RotoWire datasets. |
Reasoning Does Not Necessarily Improve Role-Playing Ability (2025.findings-acl)
Copied to clipboard
| Challenge: | a study compares zero-shot role-playing, reasoning-optimized LLMs, and reasoning-based LLM. |
| Approach: | They propose to use reasoning-optimized LLMs to improve role-playing performance . they propose to develop a chain-of-thought-based learning system that can be used to improve LLM performance if reasoning is used . |
| Outcome: | The proposed research compares zero-shot role-playing, role-playering with Chain-of-Thought, and reasoning-optimized LLMs. |
How Can Synthetic Data Improve Multilingual Language Model Pretraining? A Data Quality Perspective (2026.acl-long)
Copied to clipboard
| Challenge: | Low-resource languages are a long-tail problem for multilingual LLMs due to limited high-quality training data. |
| Approach: | They propose a method that translates high-quality, knowledge-rich English data into low-resource languages . they propose SynRank, which leverages synthetic data as positive samples to train a classifier . |
| Outcome: | The proposed method matches handcrafted rule-based filtering by human experts and significantly improves knowledge-intensive tasks with less data. |
Improving Demonstration Diversity by Human-Free Fusing for Text-to-SQL (2024.findings-emnlp)
Copied to clipboard
| Challenge: | Existing studies have explored selecting relevant demonstrations from a human-labeled demonstration pool, but these methods lack diversity and incur high labeling costs. |
| Approach: | They propose a method that iteratively fuses demonstrations to create a diverse demonstration pool based on human labeling or even from scratch with LLMs, reducing labeling costs. |
| Outcome: | The proposed method achieves an average improvement of 2.1% based on existing labeling and 5.5% from scratch on mainstream datasets. |
