Building from Scratch
A Multi-Agent Framework with Human-in-the-Loop for Multilingual Legal Terminology Mapping
This research puts forward a practical, human-AI collaborative framework designed to address the pressing need for scalable and reliable legal terminology resources—especially for less-resourced language pairs like Chinese and Japanese. Rather than relying on conventional manual approaches or purely automated tools, our workflow combines multi-agent automation with ongoing expert review, allowing for end-to-end extraction, alignment, and standardization of legal terms. In our empirical evaluation using a substantial trilingual legal corpus, this approach led to marked improvements in term coverage, semantic coherence, and contextual accuracy.

Methodology Overview: Human-AI Collaboration
Our approach integrates large language models (LLMs) and legal domain experts throughout the entire process. Unlike a single automated pipeline, we emphasize human participation in this multi-agent system. AI agents handle specific, repetitive tasks like OCR and initial extraction, while human experts provide crucial oversight, review, and supervision with contextual knowledge and legal judgment. This collaborative framework ensures high precision and consistency, particularly for challenging language pairs like Chinese and Japanese.

| Key Performance Indicator | Our Multi-Agent Framework | Traditional Manual Methods |
|---|---|---|
| Precision & Consistency | Improved significantly | Limited by human capacity |
| Scalability | Greater scalability | Labor-intensive, low scalability |
| Cost-Effectiveness | Open-source LLMs performed exceptionally well | High operational costs |
Challenge: Term Variants & Inconsistencies
Multiple translation variants and repetitive forms for the same legal concept, such as "acts of unfair competition," and inconsistencies in capitalization or granularity, complicate downstream processing. This necessitates unifying translation variants and assigning unique concept identifiers.
Challenge: Context Mismatch & Over-Extraction
LLMs sometimes misinterpret sentence boundaries or syntactic roles, leading to extraction of unintended legal terms or contextual fragments. This issue is amplified by the relative lack of explicit word boundaries in Chinese, requiring refined boundary detection algorithms and expert post-processing.
Challenge: Hallucinations
LLM-based extraction occasionally generates hallucinated terms—terms or translations not present in the original legal text or not supported by legal context. These can include inappropriate literal translations or fabrications of legal terms, undermining reliability. Robust quality control measures are crucial to mitigate this.
Future Work: Continuous Curation & Integration
The open, cloud-based "Terminology-as-a-Service" platform we developed supports continuous expert curation and can be easily integrated into various legal translation, research, and AI-powered knowledge management tools. This enables dynamic updates and adaptation to evolving legal frameworks, ensuring the resource remains current and authoritative.

Your AI Implementation Roadmap
A phased approach to integrating the Multilingual Legal Terminology Mapping Framework into your operations, ensuring a smooth transition and maximum impact.
Phase 1: Discovery & Corpus Preparation
Collaborate to define legal systems (Chinese, Japanese, English), profile user groups, negotiate information depth, and establish an update schedule. Gather and preprocess a large, balanced corpus of legal texts from authoritative sources.
Phase 2: Article Alignment & Initial Extraction
Utilize a multi-agent workflow for article-level alignment across source, target, and pivot languages (English). Employ rule-based and embedding-based methods with reranking for high-quality parallel corpus construction, followed by initial term extraction.
Phase 3: Term Mapping & Standardization
Introduce specialized intelligent agents for bilingual term extraction and auto-completion. Implement a systematic terminology standardization process, evaluating translation variants against criteria like accuracy, professionalism, and context quality, with human expert validation.
Phase 4: Quality Assurance & Platform Deployment
Conduct comprehensive human and LLM-based quality assessments across five dimensions: Coverage, Consistency, Completeness, Professionalism, and Translation Quality. Deploy the cloud-based "Terminology-As-A-Service" platform for collaborative editing and continuous updates.
