This note may be obvious to more experienced users, but I had a small difficulty because of what may be an inconsistency between the docs and the shipped example configuration.

The first example in the github README.MD shows how to specify "English" for the parser language. But in the following setup instructions, the scripts actually download the spanish version of the parser, and the English models don't seem to be present. Because of this, I got an error about missing English files.

In the super-simple installation instructions in the README, it says to run "npm explore corenlp -- npm run corenlp:download" and "npm explore corenlp -- npm run corenlp:server". As of the time of writing, the bash scripts referenced by those commands seem to install and start the Spanish version of the Stanford parser.

The upshot, I think, is one of two corrections is needed; either (1) change "English" in the example to "Spanish" and also change the English example sentence to a Spanish one, or instead (2) modify the download bash script and the server-starting bash script to fetch and run the English instead of the Spanish parser models.

I tried a version of (2) and seem to have gotten it working. In the corenlp:download script, you would change the downloaded filenames to have "-english-" where they now have "-spanish-". In the corenlp:server script, I simply remarked-out the "-serverProperties ..." line, where Spanish is specified. (I realize that now I am not specifying any serverProperties, but I will look further into that and include some as I work more with my project.)

Thanks, gerardobort, for the parser. It is a real godsend. Others may see right through this; it may be a challenge for me just because I am not yet very familiar with the software. It's up to you.
