EMNLP 2026 Submission 2026
We propose Knowledge Distribution-Optimized Synthesis (KDoS), a synthetic data framework that controls knowledge distribution, and find that an optimal knowledge distribution consistently exists across model sizes, data scales, and backbone architectures, maximizing the efficiency of scaling up LLM knowledge boundaries.

Last Layer Logits to Logic: Empowering LLMs with Logic-Consistent Structured Knowledge Reasoning
Songze Li, Zhiqiang Liu, Zhaoyan Gong, Xiaoke Guo, Zhengke Gui, Huajun Chen, Wen Zhang†
EMNLP 2026 Submission 2026
This paper presents Logits-to-Logic, a novel output-perspective approach addressing the Logic Drift of large language models (LLMs) in structured knowledge reasoning, with deeper insights into maintaining logic-consistent reasoning in LLMs.

ASTRA: Adaptive Structured Tree Reasoning Architecture for Complex Table Question Answering
Xiaoke Guo, Songze Li, Zhiqiang Liu, Zhaoyan Gong, Yuanxiang Liu, Huajun Chen, Wen Zhang†
ACL 2026 Main 2026
We introduce ASTRA, a framework that reconstructs complex tables into Logical Semantic Trees, unlocking a dual-mode reasoning capability that achieves state-of-the-art performance by effectively capturing explicit hierarchies and semantic contexts.

What's Missing in Screen-to-Action? Towards a UI-in-the-Loop Paradigm for Multimodal GUI Reasoning
Songze Li, Xiaoke Guo, Tianqi Liu, Biao Yi, Zhaoyan Gong, Zhiqiang Liu, Huajun Chen, Wen Zhang†
ACL 2026 Findings 2026
We propose UI‑in‑the‑Loop, which reformulates GUI reasoning from Screen‑to‑Action into a cyclic Screen-UI Elements-Action paradigm, and introduce the UI Comprehension task with three metrics and the 26K UI Comprehension-Bench benchmark.

CoG: Controllable Graph Reasoning via Relational Blueprints and Failure-Aware Refinement over Knowledge Graphs
Yuanxiang Liu, Songze Li, Xiaoke Guo, Zhaoyan Gong, Qifei Zhang, Huajun Chen, Wen Zhang†

Enrich-on-Graph: Query-Graph Alignment for Complex Reasoning with LLM Enriching
Songze Li, Zhiqiang Liu, Zhengke Gui, Huajun Chen, Wen Zhang†
EMNLP 2025 Main 2025
We propose Enrich-on-Graph (EoG), a flexible framework that leverages LLMs' prior knowledge to enrich knowledge graphs and bridge the semantic gap between structured KGs and unstructured queries for complex KGQA reasoning.
