LexisNexis has gone for the triple this week, with now the launch of a third AI product feature. This time it’s ‘enhanced conversational search’ in Nexis+ AI. Earlier this week they launched an agentic capability, Protégée, for workflows, and also Lexis Create+ , which leverages its Henchman acquisition for AI-based drafting. Interestingly they’ve also stressed how the use of RAG and other accuracy methods will ensure they avoid hallucinations in the new Nexis+ feature, (see below).
Launched in July 2024, Nexis+ AI is a business intelligence platform that provides AI-based tools to accelerate routine research tasks, including ‘data discovery, document analysis, report synthesis and news summarization’ – all of which may come in handy to plenty of lawyers, whether in relation to disputes or upcoming transactions.
The company said that ‘by enabling [the new] conversation-based searching across the Nexis+ AI expansive repository of licensed news publications and corporate data – including the industry’s largest collection of Gen AI-approved news datasets – it can provide digestible, multi-source responses to research questions, with linked citations to all information sources used for greater transparency’.
A traditional search results list compiled from the entire LexisNexis repository of licensed news sources is also provided, they added.
RAG methodologies are applied to enhance the precision and ‘minimize hallucinations’ – which clearly is important when it comes to news reports. For example, the recent Apple AI-generated news bulletins debacle, where it published news summaries from other sites such as the BBC, but that were totally inaccurate and included hallucinations, is a case in point.
To prevent this from happening it leverages ‘a range of automated metrics to detect hallucinations and validate relevance; a human-in-the-loop practice; and transparent citations back to original source content for quality checks and user-led validation’.
Dani McCormick, Vice President of Product, Nexis Solutions, commented: ‘Conversational search allows Nexis+ AI users to engage with our industry-leading corporate data and global news content in ways that were never possible before, rapidly delivering valuable, trustworthy business insights that lead to faster, more accurate business decisioning and increased market competitiveness.’
‘Designing thoughtfully by respecting the integrity of publisher and user data enables us to deliver practical, time-saving AI solutions that solve a multitude of business challenges for our customers.’
All-in-all a very busy time for LexisNexis across its legal and adjacent products – and all deeply based upon genAI capabilities.
Of course we can now expect Thomson Reuters and others to respond.
