AutoFigure: Generating and Refining Publication-Ready Scientific Illustrations

ICLR 2026poster

High-quality scientific illustrations are crucial for effectively communicating complex scientific and technical concepts, yet their manual creation remains a well-recognized bottleneck in both academia and industry. We present FigureBench, the first large-scale benchmark for generating scientific i…

Structural Entropy Guided Agent for Detecting and Repairing Knowledge Deficiencies in LLMs

NeurIPS 2025poster

Large language models (LLMs) have achieved unprecedented performance by leveraging vast pretraining corpora, yet their performance remains suboptimal in knowledge-intensive domains such as medicine and scientific research, where high factual precision is required. While synthetic data provides a pro…

Towards Effective, Efficient and Unsupervised Social Event Detection in the Hyperbolic Space

AAAI 2025technical

The vast, complex, and dynamic nature of social message data has posed challenges to social event detection (SED). Despite considerable effort, these challenges persist, often resulting in inadequately expressive message representations (ineffective) and prolonged learning durations (inefficient). I…

DA-Code: Agent Data Science Code Generation Benchmark for Large Language Models

EMNLP 2024main

We introduce DA-Code, a code generation benchmark specifically designed to assess LLMs on agent-based data science tasks. This benchmark features three core elements: First, the tasks within DA-Code are inherently challenging, setting them apart from traditional code generation tasks and demanding a…

EX-FEVER: A Dataset for Multi-hop Explainable Fact Verification

ACL 2024findings

Fact verification aims to automatically probe the veracity of a claim based on several pieces of evidence. Existing works are always engaging in accuracy improvement, let alone explainability, a critical capability of fact verification systems.Constructing an explainable fact verification system in…

Neeko: Leveraging Dynamic LoRA for Efficient Multi-Character Role-Playing Agent

EMNLP 2024main

Large Language Models (LLMs) have revolutionized open-domain dialogue agents but encounter challenges in multi-character role-playing (MCRP) scenarios. To address the issue, we present Neeko, an innovative framework designed for efficient multiple characters imitation. Neeko employs a dynamic low-ra…

MenatQA: A New Dataset for Testing the Temporal Comprehension and Reasoning Abilities of Large Language Models

EMNLP 2023long findings

Large language models (LLMs) have shown nearly saturated performance on many natural language processing (NLP) tasks. As a result, it is natural for people to believe that LLMs have also mastered abilities such as time understanding and reasoning. However, research on the temporal sensitivity of LLM…

S3HQA: A Three-Stage Approach for Multi-hop Text-Table Hybrid Question Answering

ACL 2023short

Answering multi-hop questions over hybrid factual knowledge from the given text and table (TextTableQA) is a challenging task. Existing models mainly adopt a retriever-reader framework, which have several deficiencies, such as noisy labeling in training retriever, insufficient utilization of heterog…
