LexisNexis Enhances Lexis+ AI with New Features, AI Models, and Graph Technology to Further Drive High Quality, Trusted Answers for Legal Professionals

Enhancements deliver trusted results and an increasingly personalized generative AI experience, giving customers greater control over their prompts, jurisdictions, and search history

CHICAGO, IL—American Association of Law Libraries 2024 (Booth #604) — LexisNexis^® Legal & Professional, a leading global provider of information and analytics, today announced a powerful set of customer-driven enhancements to the industry-leading Lexis+ AI^™ that reinforce the company’s commitment to delivering high-quality, trusted results. Based on continuous user feedback, these new capabilities harness generative AI to streamline legal research, provide comprehensive, current legal analysis, and save time so legal professionals can focus on higher-value work.

Grounded in the world’s largest repository of up-to-date, exclusive legal content from LexisNexis, Lexis+ AI enables conversational search, insightful summarization, intelligent legal drafting, and document upload and analysis capabilities in a seamless user experience.

All recent and upcoming enhancements are based on customer-led development.

Usability enhancements include:

• “Stop Response” Option – Gives users more control over the AI assistant’s actions, allowing them to halt responses if they need to make changes to their prompts, which will save them valuable time.
• Default Jurisdiction – Users can now set a jurisdiction as their default jurisdiction, which allows it to appear pre-selected each time they access the jurisdiction panel for seamless workflow.
• History – A new conversation history feature enables users to easily find, review, and re-run previous conversations with the AI assistant.
• Lexis+ AI Uploads Grid View – Streamlines the research process by displaying answers from multiple user-uploaded documents on a single screen for clear side-by-side comparisons and efficient insights.

Legal research and drafting enhancements include:

• Lexis+ AI Headnotes – Uses advanced AI technology to provide comprehensive headnote coverage for every case across the entire collection, allowing users to quickly grasp key points of law and easily locate similar cases, ensuring no critical legal insights are missed.
• Shepardize^® Uploaded Documents – Users can run the renowned Shepard’s^® Citation Service directly within their uploaded documents using the AI assistant. This provides access to the full Brief Analysis report, identifying weaknesses in opposing arguments and strengthening their case.
• Shepard’s Treatment Summaries – Enables users to quickly determine if a case is relevant with at-a-glance summaries and seamlessly access the full Shepard’s report.
• Legal News Integration – Direct access to premium legal news content is now integrated into the AI assistant, complementing existing legal research capabilities for comprehensive legal analysis in one solution.

Retrieval Augmented Generation (RAG) enhancements now include:

• Integration of advanced Shepard’s^® Knowledge Graph to the proprietary LexisNexis RAG platform (GraphRAG) – Users can harness the power of highly accurate Shepard’s^® case law relationship information to deliver more authoritative, complete and final AI-generated responses.
• Shepard’s^® Knowledge Graph is a sophisticated data organization framework that allows users to:
  • Precisely identify the most relevant data from extensive Lexis legal sources.
  • Receive complete answers based on connections between related opinions, legal taxonomies, and additional metadata that enhance the quality and context of responses.
  • Accurately verify citations, case connections and legal concepts as validated by the Shepard’s^® Citations Service.
  • Reduce research time and improve confidence and trust through measurably better answer quality.

Large Language Models added as part of our multi-model approach include:

• Claude 3 models by Anthropic, hosted on Amazon Bedrock from Amazon Web Services (AWS)
• GPT-4o, hosted on Microsoft Azure OpenAI
• Fine-tuned Mistral 7B, an open-source model, hosted on LexisNexis-managed servers within AWS

“At LexisNexis, customers are at the heart of our continuous generative AI development,” said Sean Fitzpatrick, CEO of LexisNexis North America, UK, and Ireland. “We are rapidly introducing customer-driven enhancements as part of our ongoing commitment to improve the user experience and deliver the most value for our customers.”
