Which NLP library among the following ones below is the most mature and should be used in a scaled project of text processing.
In my project I am designing a full infrastructure of unstructured text processing, and there are scenarios where none of the available libraries can be leveraged, therefore I am implementing my own solution, however, I want to make evaluation against the current state of the art NLP libraries. and I want to pick up the most mature ones.
Thank you in advance.
Hassan.
