Installing Stanford Core NLP package on Mac OS X

I am following instructions on the GitHub page of Stanford Core NLP under Build with Ant. To install ant, you can use homebrew:

$ brew install ant

In Step 5, you have to include the .jar files in the directory CoreNLP/lib and CoreNLP/liblocal in your CLASSPATH. To do this, first, I install coreutils:

brew install coreutils

such that I can use the utility realpath there. Then, I include the following in my ~/.bashrc:

for file in `find /Users/clare.huang/CoreNLP/lib/ -name "*.jar"`;
  do export CLASSPATH="$CLASSPATH:`realpath $file`";
done

for file in `find /Users/clare.huang/CoreNLP/liblocal/ -name "*.jar"`;
  do export CLASSPATH="$CLASSPATH:`realpath $file`";
done

(I guess there are better ways to combine the commands above. Let me know if there are.)

To run CoreNLP, I have to download the latest version of it, and place it in the directory CoreNLP/:

wget http://nlp.stanford.edu/software/stanford-corenlp-full-2018-01-31.zip

The latest version is available on their official website. Unzip it, and add all the .jar there to the $CLASSPATH.

Afterwards, you shall be able to run CoreNLP with the commands provided in the blogpost of Khalid Alnajjar (under Running Stanford CoreNLP Server). If you have no problem starting the server, you shall be able to see the interface on your browser at http://localhost:9000/:

java -mx4g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -annotators "tokenize,ssplit,pos,lemma,parse,sentiment" -port 9000 -timeout 30000

Yay. Next, I will try setting up the python interface.
