Watson Developer Cloud


AlchemyLanguage is a collection of text analysis functions that derive semantic information from your content. You can input text, HTML, or a public URL and leverage sophisticated natural language processing techniques to get a quick high-level understanding of your content and obtain detailed insights such as directional sentiment from entity to object.

If you want to try these functions and see what's possible with AlchemyLanguage for yourself, check out the demo app and its companion GitHub repo.

We are always looking to improve and learn from your experience with our services. You can submit comments or ask questions about the AlchemyLanguage API in the Watson forum. You can also read posts about Watson services that are written by IBM researchers, developers, and other experts on the Watson blog.
