Beyond Guilt: Legal Judgment Prediction with Trichotomous Reasoning

EMNLP 2025

In legal practice, judges apply the trichotomous dogmatics of criminal law, sequentially assessingthe elements of the offense, unlawfulness, and culpability to determine whether an individual’s conduct constitutes a crime. Although current legal large language models (LLMs) show promising accuracy i

Legal Mathematical Reasoning with LLMs: Procedural Alignment through Two-Stage Reinforcement Learning

EMNLP 2025

Legal mathematical reasoning is essential for applying large language models (LLMs) in high-stakes legal contexts, where outputs must be both mathematically accurate and procedurally compliant. However, existing legal LLMs lack structured numerical reasoning, and open-domain models, though capable o

Trigger3:Refining Query Correction via Adaptive Model Selector

AAAI 2025technical

In search scenarios, user experience can be hindered by erroneous queries due to typos, voice errors, or knowledge gaps. Therefore, query correction is crucial for search engines. Current correction models, usually small models trained on specific data, often struggle with queries beyond their train…

Effective In-Context Example Selection through Data Compression

ACL 2024findings

In-context learning has been extensively validated in large language models. However, the mechanism and selection strategy for in-context example selection, which is a crucial ingredient in this approach, lacks systematic and in-depth research. In this paper, we propose a data compression approach t…

Logic Rules as Explanations for Legal Case Retrieval

COLING 2024main

In this paper, we address the issue of using logic rules to explain the results from legal case retrieval. The task is critical to legal case retrieval because the users (e.g., lawyers or judges) are highly specialized and require the system to provide logic, faithful, and interpretable explanations…
