Salience Engine™

Salience is an on-premise, multi-lingual text analysis engine.

Salience integrates into your application to handle text analysis and opinion mining in deep, fundamentally meaningful ways.


Three billion documents per day pass through the Lexalytics Salience Engine, helping some of the world's largest companies make well-informed decisions.

We're also the first company to bring Sentiment Analysis to the market, and have been at this for over 11 years.

Check out some of the big names we power at the bottom of this page.


Salience provides more granularity than any other installed solution. We would know, we've checked. Each theme, classifier, entity, and document comes with its own sentiment score. 

It's completely transparent, so you can pinpoint where the sentiment comes from and tune it.

We also have preconfigured modes for short content like Twitter and Ebay feedback.


Every aspect of Salience can be customized to suit your needs. 

Train the Categorization to tag limitless categories. List the Entities you need to extract, augmenting Salience's ability to find them. Adjust Sentiment Analysis to fit specific industry sentiment vocabulary.

Develop new patterns to expose Relationships between Entities. And that's just the tip of the iceberg.


Works extremely well right out of the box. Salience has been pre-trained on Wikipedia to classify against any taxonomy, so you don't have to.

All you need to do is integrate Salience with your application, and you're ready to roll. No knowledge of NLP or linguistics required.

Or you can get started right away with our SaaS product Semantria.
