Writing sentiment analysis results to XML

[alexweissman]

I'm having trouble figuring out how to get the sentiment analysis tool to output as an XML file when run from the command line. When I run the command provided on http://www-nlp.stanford.edu/sentiment/code.html it works fine but only outputs plain text:

Adding annotator tokenize

Adding annotator ssplit

Adding annotator parse

Loading parser from serialized file edu/stanford/nlp/models/lexparser/englishPCFG.ser.gz ... done [1.3 sec].

Adding annotator sentiment

This is so great.

  Very positive

It was okay I guess.

  Neutral

However if I try to run the full CoreNLP tool with the sentiment annotator, like such:

java -cp stanford-corenlp-full-2013-11-12/stanford-corenlp-3.3.0.jar:stanford-corenlp-full-2013-11-12/stanford-corenlp-3.3.0-models.jar:stanford-corenlp-full-2013-11-12/xom.jar:stanford-corenlp-full-2013-11-12/joda-time.jar:stanford-corenlp-full-2013-11-12/jollyday.jar -Xmx3g edu.stanford.nlp.pipeline.StanfordCoreNLP -annotators tokenize,ssplit,parse,sentiment -file  ./tweets/tweet1.txt

I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/ejml/simple/SimpleBase

    ... 7 more

If I run the command without the sentiment annotator, it works fine but of course I can't get any sentiment results.

I should also mention that I am running everything wrapped inside a Python subprocess.Popen() call, since the rest of our project is written in Python.

Need to include the ejml library in your classpath

That works, thank you!

Would it be possible to add an extra column to the table on http://nlp.stanford.edu/software/corenlp.shtml that lists which libraries are required for each annotator? Thanks again.
