Why Trustworthy AI Is the Key to Unlocking Technology's True Potential

Deriving the value hidden in text - Feel the Power of IBM Watson Natural Language Understanding!

Humans use words to talk and write.  Well, sometimes computers have a hard time understanding all those words like we do. Natural Language Understanding, or NLU for short, is like a special tool that helps computers understand our words better. It includes a set of text analytics features that you can use to extract meaning from unstructured data. 

IBM Watson® Natural Language Understanding employs deep learning to derive meaning and metadata from unstructured text data. Delve into your data using text analytics, and extract categories, classification, entities, keywords, sentiment, emotion, relations, and syntax.

Natural Language Understanding stands as a premier text analytics service, seamlessly integrable into your existing data pipeline. It  supports 13 languages based on the feature. NLU is hosted in Dallas, Washington, D.C., Frankfurt, and Sydney.
