It has all information needed for working online with this platform in detail! You can integrate into your project, learn very well about its interface by using tutorials provided as part of documentation - excellent job! Very user friendly library which includes an extensive set of examples; I recommend to everyone who have limited programming language skills but still need powerful software with great UI / UX or integration possibilities. What's missing? Nothing specific at the moment because everything works out smoothly so far - just make sure you choose appropriate tools/libraries before starting implementation process. We implemented several functions from our system powered through this Library, especially text mining tasks related to customer feedback (e.g., sentiment analysis) are successfully executed thanks to such advanced toolset we used within CogNlp. The accuracy of this tool is amazing. I was able to build an application with this tool, that can identify customers from their voice. It's very easy to use as well. This software is not expensive at all. You will be surprised! I have used this software for building my own app. It has been very beneficial for me. I am able to extract data from voice recordings.
