仅从corenlp服务器调用openie模块

Question

I'd like to invoke only the openIE module once coreNLP server is up. I tried this from shell:

$ java -mx4g -cp "$HOME/corenlp/*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer &
$ java -cp "$CORE/*" -Xmx1g edu.stanford.nlp.pipeline.StanfordCoreNLPClient edu.stanford.nlp.naturalli.OpenIE -file inputfile.txt

After a few seconds, logs get freeze and nothing happens. Can someone help me please?

You can't do that with the StanfordCoreNLPClient, you need to run a pipeline. You can find full instructions for using the client here:

http://stanfordnlp.github.io/CoreNLP/corenlp-server.html

For example:

java -Xmx4g edu.stanford.nlp.pipeline.StanfordCoreNLPClient -cp "*" -annotators tokenize,ssplit,pos,lemma,ner,depparse,natlog,openie -file input.txt  -backends localhost:9000 

Note that the OpenIE extractor requires everything in the pipeline prior to it, so there is not an extra cost to running this part of the pipeline: tokenize,ssplit,pos,lemma,ner,depparse,natlog
