Is a server really necessary?

[steve3p0]

Can someone explain to me why a server is required to use py-corenlp?

The server is to host the CoreNLP using java and then the package is doing corenlp by calling the server you hosted. This make the inference much faster than using the original nltk-way, which doesn't run the server and uses the corenlp jar files in python.
