Lexalytics Enhances Salience Engine

Lexalytics, Inc. (, a software and services company specializing in text analytics and social media monitoring, has released Salience 4.0. This latest version of the Salience Engine marks the first major software release for Lexalytics since the merger with Infonic’s Text Analytics Division. The new version offers significant improvements to entity extraction, sentiment scoring, and thematic extraction, as well as several new features. Salience technology is widely used by professionals in the marketing, public relations, enterprise search, and financial services industries to manage brand reputation and improve the business value of information.

The Salience 4.0 software delivers a new inferred entity engine which will allow companies to identify products and brands from within text without the use of massive product lists or dictionaries. Salience 4.0 also allows for better entity recognition, with initial test results showing up to 90 % accuracy for people and more than 80 % for companies. Improvements also include the ability to detect entity relationships. For example, "John Smith is CEO of XYZ Co. which is located in Amherst, Mass.," would show relationships between John Smith, his company, the location, and his job title.

Salience 4.0 includes two new enhancements to sentiment scoring: adjective amplifiers and coreference. Adjective amplifiers solve problems in text such as "perfectly awful," where the two descriptors would normally negate each other for sentiment. The coreference enhancement will draw correlations between a person and a pronoun such as, "John Smith is being promoted. He has taken a new position as CEO." It will recognize that "he" is "John Smith."

Lastly, Salience 4.0 has dramatically improved the theme extraction capabilities and will return longer themes or concepts from a document with more accuracy to the subject matter, and it can role those themes up to a parent theme more easily. The result is delivery of data to the user that immediately provides relevant context around the entities and themes with which they are associated, arming business leaders with the ability to monitor and react quickly.
