UK’s RELX Achieves Double-Digit Growth with Generative AI Tools — Comprehensive Utilization and Business Deployment

Executive Summary

• UK information services giant RELX reported a 9% increase in operating profit and a 7% increase in revenue for the first half of 2025.
• This growth was driven by the legal AI assistant Lexus+AI Protégé and the researcher-focused information analysis tool Science Direct AI.
• Lawyers and corporate legal departments are using these tools for “draft generation” and “automated summarization,” while research institutions deploy them for “literature reviews” and “topic exploration.”
• RELX aims to further boost revenue through “new content,” “expanded data sources,” and “algorithmic innovation.”

1. Flagship Tool ①: Lexus+AI Protégé (formerly LexisNexis Protégé)

• Features:
  • Automated Draft Generation of legal documents (contracts, legal opinions, pleadings, etc.)
  • Summarization and Key Point Extraction of existing documents
  • Natural Language Explanations of cross-referenced case law and statutes
• Use Cases:
  • Enables lawyers to prepare client- and court-facing materials quickly, reducing document creation time by 30–40% per case.
  • Allows compliance teams to run bulk contract reviews via AI, minimizing human error.
• Impact:
  • The precision of generative AI summaries and drafts lets experts focus solely on the “final review.”
  • Pre-training on custom models for each specialty ensures seamless handling of industry-specific terminology and formats.

2. Flagship Tool ②: Science Direct AI

• Features:
  • Automated Summarization and Translation of scholarly articles
  • Topic Clustering across multiple papers
  • Dashboard Display of the latest research trends
• Use Cases:
  • University and corporate R&D teams can grasp key messages from vast literature in under one minute.
  • AI-driven prior art reviews in drug development and materials research streamline lead times.
• Impact:
  • Researchers are freed from routine “search → summarize → evaluate” tasks, enabling them to focus on creative experiment design and analysis.
  • Multilingual support bridges information gaps in global collaborative research.

3. Integration of Generative AI with Existing Solutions

• Platform Integration: Both tools are managed through the unified Lexis+ AI ecosystem.
• Security & Compliance: Built-in data governance features comply with FERPA and GDPR, ensuring strict control over confidential information.
• User Training: Webinars and hands-on workshops launched immediately after release to drive adoption internally.

4. Future Outlook and Challenges

• New Content Expansion: Plans to add financial and healthcare reports, as well as industry-specific templates.
• Data Source Growth: Strengthening real-time integration with public databases and proprietary datasets.
• Algorithmic Innovation: Implementing self-improvement via reinforcement learning to continuously enhance response accuracy and reliability.
• Challenges: Preventing hallucinations in AI outputs and addressing explainability (XAI) remain top priorities.

Conclusion

1. RELX’s double-digit growth is the result of practical implementation and solid adoption of generative AI tools.
2. Lexus+AI Protégé and Science Direct AI have automated routine tasks in legal and research settings, dramatically boosting specialist productivity.
3. Future drivers will include content expansion, data integration, and algorithmic innovation.
4. Companies must establish robust accountability and quality governance measures alongside adoption to ensure successful AI deployment.
