Fast, Powerful, and Totally Customizable

Integrate Salience into your enterprise business intelligence architecture or white label it inside your own data analytics product.

Fast and Powerful.


Salience can process 200 tweets per second while scaling from single process cores to entire data centers with a small memory footprint. Use Java, Python, .NET/C# bindings for higher level ease or the native C/C++ interface for maximum speed.


Enjoy full access to the underlying technology. Tune every text analytics function and NLP feature, from tokenization and part of speech tagging to sentiment scoring, categorization, theme analysis and more.


Built on a pipeline model of NLP rules and machine learning models. When issues arise, see exactly where they are in the pipeline. Adjust specific features without disrupting the larger system.


Salience runs entirely on your servers, while staying flexible enough to offload insensitive data to cloud servers to reduce your processing costs. Enjoy native compliance with most data security and privacy regulations.
