ConnectionRefusedError: [Errno 111] Connection refused

[gandharvsuri]

I've used Docker to set up the repository and trying to run the code snipped under 'Usage' in the readme.

I'm new to docker so please confirm if I'm doing it correctly. I first run the 'docker run' command and turn on the stranford_corenlp server. Then on another terminal, I run my code snippet.
I get the following error.
