Lexalytics
From AltData.wiki, The Alternative Data Encyclopedia
Lexalytics is an American text analytics and natural language processing company that supplies sentiment analysis, entity extraction, categorization and intention detection technology to other software vendors and enterprises.[1] Its core engine, Salience, is available as an on-premise library, while the Semantria product delivers the same capabilities through a cloud API, and the Spotlight platform adds storage, management and visualization of unstructured documents.[1][4].
Founded in January 2003 and headquartered in the Boston area, Lexalytics operated independently for nearly two decades before being acquired by customer experience company InMoment in September 2021, and continues to operate under its own brand.[2][3] Its engine has been embedded by social media monitoring firms and has been used for news sentiment analysis related to stock trading.[2]
What It Does
The company sells NLP infrastructure rather than end-user dashboards: developers integrate Salience or Semantria into their own products to determine sentiment, extract entities such as people, companies and products, categorize documents into taxonomies, detect expressed intentions and summarize texts.[1] Pre-built Industry Packs tune accuracy for verticals including hotels, restaurants, retail and pharmaceuticals, with the pharma pack mapping ICD-10 codes to normalized terminology.[1]
Data And Methodology
Salience combines rule-based linguistic processing with machine learning components, including hundreds of deployed models and custom-trained "micromodels" for client-specific problems.[1] A distinctive feature described in press coverage is the concept matrix, built from processing the entire repository of Wikipedia, which allows the engine to understand relationships between concepts and support automatic categorization.[2] The platform offers native language support in 29 languages according to the company's website.[1]
Products
The portfolio comprises Salience for on-premise deployment, Semantria as a RESTful cloud API with configuration and user management tooling, Spotlight for storing and analyzing document collections with interactive dashboards, and semi-custom application development plus professional services.[1] In 2018 the company entered the document data extraction market using NLP.[2]
Buyers And Use Cases
Documented customers and partners include Thomson Reuters, Oracle, Salesforce, DataSift and Bottlenose, with the Salience engine frequently embedded directly inside social media monitoring products.[2] Applications span voice-of-customer analytics, reputation management, regulatory compliance involving complex text documents, robotic process automation and medical affairs AI.[1] Wall Street use of its sentiment scoring for trading was profiled by Forbes in 2011.[2]
History
Lexalytics was spun out in January 2003 from content management startup Lightspeed when Lightspeed consolidated on the West Coast; Lightspeed general manager Jeff Catlin and principal engineer Mike Marshall took over the East Coast operation, renaming it Lexalytics, with Catlin as CEO and Marshall as CTO.[2] The company declined venture funding and initially shared sales costs with UK document management firm Infonic.[2] It acquired cloud text mining startup Semantria, founded by former Lexalytics marketing director Oleg Rogynskyy, in 2014 in a deal reported at less than $10 million.[2] InMoment completed its acquisition of Lexalytics in September 2021, and in 2023 the unit was named Best Overall NLP Company at the AI Breakthrough Awards as it marked its 20th anniversary.[3][1]
