This a Python wrapper for Stanford University's NLP group's Java-based CoreNLP tools. It can either be imported as a module or run as an JSON-RPC server. Because it uses many large trained models (requiring 3GB RAM and usually a few minutes loading time), most applications will probably want to run it as a server.
There's not much to this script.
It requires pexpect.
This uses jsonrpc and python-progressbar, which are included in this repository.
You should have downloaded and unpacked the tgz file containing Stanford's Core-NLP package. Then copy all of the python files from this repository into the stanford-corenlp-2010-11-12 folder.
Then, to launch a server:
python server.py
Optionally, specify a host or port:
python server.py -H 0.0.0.0 -p 3456
To run a public JSON-RPC server on port 3456.
See client.py for example of how to connect with a client.
I have only tested this on Core NLP tools version 1.0.2 released 2010-11-12.
If you think there may be a problem with this wrapper, first ensure you can run the Java program:
java -cp stanford-corenlp-2010-11-12.jar:stanford-corenlp-models-2010-11-06.jar:xom-1.2.6.jar:xom.jar:jgraph.jar:jgrapht.jar -Xmx3g edu.stanford.nlp.pipeline.StanfordCoreNLP -props default.properties
