Below are interfaces and packages for running Stanford CoreNLP from other languages or within other packages. They have been written by many other people (thanks!). In general you should contact these people directly if you have problems with these packages.




Okay, Docker isn’t a language, but you know what we mean…. Note on running the CoreNLP server under docker: The container’s port 9000 has to be published to the host. Give a command like: docker run -p 9000:9000 --name coreNLP --rm -i -t motiz88/corenlp. If, when going to localhost:9000/, you see the error This site can’t be reached. localhost refused to connect, then this is what you failed to do!


  • corenlp by Robert Bates provides a thin client interface in Erlang to a CoreNLP server. GitHub.


JavaScript (node.js)

Other choices are now probably best avoided:

  • corenlp-js-interface is the simplest interface with CoreNLP server in node.js. The GitHub site is no longer available.
  • corenlp-js-prefab a simple interface to the CoreNLP server with a prefab function so you only have to send text no extra parameters with each call. By Noah Dessauer. The GitHub site is no longer available.
  • stanford-corenlp-node (github site) is a webservice interface to CoreNLP in node.js by Mike Hewett. No recent development.
  • stanford-simple-nlp (github site) is a node.js CoreNLP wrapper by Taeho Kim (xissy). This doesn’t seem to have been updated lately. You’re better off with something else.








Thrift server

ZeroMQ/ØMQ servers

  • stanford-0mq by Diane Napolitano. An implementation of a server for Stanford’s CoreNLP suite using Ømq and a basic client/server/JSON requests configuration. Last commit: Oct 2015.
  • stanford-corenlp-zeromq by URXtech. Basic JSON wrapper around CoreNLP.
  • corenlp-zmq by Thom Neale. A Dockerfile and Ansible provisioning script to build and run a Stanford CoreNLP server process with a single ZMQ broker font-end that proxies incoming requests to one or more back-end Scala workers. Last commit: 2015.
  • corenlp-server by Eric Kow. Simple Java server communicating with clients via XML through ZeroMQ. Example Python client included. Last commit: 2014.
