How to run NegAIT with Stanford core nlp in Java in terminal in Mac?

I am not familiar with Java (only python). But I'd like to run NegAIT.

I have stanford core nlp 3.7 installed & downloaded the NegAIT repository. They're both in my home directory. I also have JDK SE 1.8 set as my home path.

When I ran the command on my Macbook terminal inside the NegAIT-master folder:

java -cp negate.jar:/Users/username/NegAIT-master/stanford-corenlp-3.7.0/stanford-corenlp-3.7.0.jar:/Users/username/NegAIT-master/stanford-corenlp-3.7.0/stanford-corenlp-3.7.0-models.jar negate.NegationParser AagenaesSyndrome.txt AagenaesSyndromeNegation

I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: edu/stanford/nlp/pipeline/StanfordCoreNLP
    at negate.TextRead.<init>(TextRead.java:48)
    at negate.NegationParser.main(NegationParser.java:21)
Caused by: java.lang.ClassNotFoundException: edu.stanford.nlp.pipeline.StanfordCoreNLP

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 2 more

As I said, I am familiar with Python but not with Java, if someone could help me out or give me a tip on how to run this tool I would highly appreciate it.

Solution

  • Stanford CoreNLP is not being found on your CLASSPATH. It looks like that is because you haven't substituted your login name for username in the paths in the -cp.

    Or, if you are in running the commend inside the NegAIT-master folder, and the CoreNLP jar files are in a subdirectory stanford-corenlp-3.7.0 from there, you could simplify the CLASSPATH to:

    java -cp negate.jar:stanford-corenlp-3.7.0/stanford-corenlp-3.7.0.jar:stanford-corenlp-3.7.0/stanford-corenlp-3.7.0-models.jar negate.NegationParser AagenaesSyndrome.txt AagenaesSyndromeNegation
