Can Large Language Models Understand You Better? An MBTI Personality Detection Dataset Aligned with Population Traits

COLING 2025main

The Myers-Briggs Type Indicator (MBTI) is one of the most influential personality theories reflecting individual differences in thinking, feeling, and behaving. MBTI personality detection has garnered considerable research interest and has evolved significantly over the years. However, this task ten…

DAC: Decomposed Automation Correction for Text-to-SQL

EMNLP 2025

Text-to-SQL is an important task that helps access databases by generating SQL queries. Currently, correcting the generated SQL based on large language models (LLMs) automatically is an effective method to enhance the quality of the generated SQL. However, previous research shows that it is hard for

MURRE: Multi-Hop Table Retrieval with Removal for Open-Domain Text-to-SQL

COLING 2025main

The open-domain text-to-SQL task aims to retrieve question-relevant tables from massive databases and generate SQL. However, the performance of current methods is constrained by single-hop retrieval, and existing multi-hop retrieval of open-domain question answering is not directly applicable due to…

NoisyRollout: Reinforcing Visual Reasoning with Data Augmentation

NeurIPS 2025poster

Recent advances in reinforcement learning (RL) have strengthened the reasoning capabilities of vision-language models (VLMs). However, enhancing policy exploration to better scale test-time compute remains largely underexplored. In addition, VLMs continue to struggle with imperfect visual perception…

RegMix: Data Mixture as Regression for Language Model Pre-training

ICLR 2025spotlight

The data mixture for large language model pre-training significantly impacts performance, yet how to determine an effective mixture remains unclear. We propose RegMix to automatically identify a high-performing data mixture by formulating it as a regression task. RegMix trains many small models on d…

SCITAT: A Question Answering Benchmark for Scientific Tables and Text Covering Diverse Reasoning Types

ACL 2025finding

Scientific question answering (SQA) is an important task aimed at answering questions based on papers. However, current SQA datasets have limited reasoning types and neglect the relevance between tables and text, creating a significant gap with real scenarios. To address these challenges, we propose…

Unnatural Languages Are Not Bugs but Features for LLMs

ICML 2025poster

Large Language Models (LLMs) have been observed to process non-human-readable text sequences, such as jailbreak prompts, often viewed as a bug for aligned LLMs. In this work, we present a systematic investigation challenging this perception, demonstrating that unnatural languages - strings that appe…

Enhancing Numerical Reasoning with the Guidance of Reliable Reasoning Processes

ACL 2024long

Numerical reasoning is an essential ability for NLP systems to handle numeric information. Recent research indicates that fine-tuning a small-scale model to learn generating reasoning processes alongside answers can significantly enhance performance. However, current methods have the limitation that…

Exploring Equation as a Better Intermediate Meaning Representation for Numerical Reasoning of Large Language Models

AAAI 2024technical

Numerical reasoning is a vital capability for natural language processing models to understand and process numerical information in real-world scenarios. Most current methods first generate the Intermediate Meaning Representations (IMRs) of questions and then generate answers. Current SOTA methods g…

Improving Demonstration Diversity by Human-Free Fusing for Text-to-SQL

EMNLP 2024finding

In-context learning with large language models (LLMs) is the current mainstream method for text-to-SQL. Previous studies have explored selecting relevant demonstrations from a human-labeled demonstration pool, but these methods lack diversity and incur high labeling costs. In this work, we address m…

Sailor: Open Language Models for South-East Asia

EMNLP 2024system demonstrations

We present Sailor, a family of open language models ranging from 0.5B to 14B parameters, tailored for South-East Asian (SEA) languages. From Qwen1.5, Sailor models accept 200B to 400B tokens during continual pre-training, primarily covering the languages of English, Chinese, Vietnamese, Thai, Indone…

Scaling Laws with Vocabulary: Larger Models Deserve Larger Vocabularies

NeurIPS 2024poster

Research on scaling large language models (LLMs) has primarily focused on model parameters and training data size, overlooking the role of vocabulary size. We investigate how vocabulary size impacts LLM scaling laws by training models ranging from 33M to 3B parameters on up to 500B characters with v…

MultiSpider: Towards Benchmarking Multilingual Text-to-SQL Semantic Parsing

AAAI 2023technical

Text-to-SQL semantic parsing is an important NLP task, which facilitates the interaction between users and the database. Much recent progress in text-to-SQL has been driven by large-scale datasets, but most of them are centered on English. In this work, we present MultiSpider, the largest multilingu…

Towards Knowledge-Intensive Text-to-SQL Semantic Parsing with Formulaic Knowledge

EMNLP 2022main

In this paper, we study the problem of knowledge-intensive text-to-SQL, in which domain knowledge is necessary to parse expert questions into SQL queries over domain-specific tables. We formalize this scenario by building a new benchmark KnowSQL consisting of domain-specific questions covering vario…
