Lexalytics - Text Analysis Software Libraries

Lexalytics provides a multi-lingual text analysis engine. 

They write about themselves and their Salience Engine on their website:

"Lexalytics builds a text analysis engine that's entirely purposed for OEM integration into your application or service."

"Salience configuration is extremely sophisticated, allowing for tuning at arbitrarily fine levels.  We have provided a number of different pre-configured data directories for your processing pleasure.  We have one that's optimized for Twitter, and one for longer-form content.   Languages are also treated simply as data directories, integrating very cleanly with the rest of your installation."
