LexisNexis® Legal & Professional,  announced over a dozen new Lexis+ AI  features during the American Association of Law Libraries Meeting & Conference this week.

Lexis+ AI offers conversational search, insightful summarization, intelligent legal drafting, and document upload and analysis capabilities in a seamless user experience. The new features highlighted in the press release were developed based on customer feedback.

In a live briefing during the conference, Serena Wellen, VP of Product Management emphasized the “human in the loop” aspect of LN’s AI development strategy in order to assure that responses are accurate, not hallucinated, responsive to the researchers intent, complete, authentic and composed using an appropriate “tone.” She also noted that Lexis + AI can now respond to up to 10 conversational “turns.” She claims that Lexis + AI is two times faster than their nearest competitor. I love these kinds of comparisons but I can’t wait for some 3 party market studies to verify the speed of various GAI product responses when performing similar tasks.

Here are the new features included in the press release:

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 verifiy 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
