Text-Processing.com is a natural language service. Using semantic and sentiment analysis, the service provides tools for determining meaning behind text.
The text-processing.com API is a service for text mining and natural language processing. It is currently free and open for public use without authentication, though that may change in the future.
The API uses a simple HTTP protocol with JSON data format.
Now I don’t have a master’s degree in Natural language processing, and you just might need one to get your hands dirty with this API. I see the text-processing.com API as offering a mid-level utility for incorporation in a web app. You might take text samples from your source, feed them through the Text-Processing API and analyze those results a bit further before presenting anything to your user.
