IBM Natural Language Understanding is now underpinned by the same technology that powers IBM Research's Project Debater with new enhancements to Watson Discovery expected this year. This marks the first commercial release of key NLP capabilities from IBM Research's Project Debater -- these new capabilities include advanced sentiment analysis, topic clustering, and data summarization features. 

Get more value out of unstructured data with natural language processing

Natural language processing (NLP) is one area of artificial intelligence using computational linguistics that provides parsing and semantic interpretation of text, which allows systems to learn, analyze, and understand human language. With Watson's suite of NLP offerings, including Watson Natural Language Understanding (NLU), you can surface concepts, categories, sentiment, and emotion, and apply knowledge of unique entities in your industry to your data, no matter where it lives.

Optimize your advertising with NLP

Ensure proper placement of advertisements based on page content, viewer patterns, and sentiment analysis of social media and other content.
