Example code fails with "Error creating > edu.stanford.nlp.time.TimeExpressionExtractorImpl" when using Stanford CoreNLP version 3.5.1

[mike-a-ellis]

I am trying to learn the Stanford CoreNLP library. I am using C# with the posted example (https://sergey-tihon.github.io/Stanford.NLP.NET/StanfordCoreNLP.html). I loaded the package “Stanford.NLP.CoreNLP” (it added IKVM.NET) via nuget and downloaded the code. Unzipped the .jar models. My directory is correct. I get the following error:

Here is my code:

// Text for processing
var text = "Kosgi Santosh sent an email to Stanford University. He didn't get a reply.";

// Annotation pipeline configuration
var props = new Properties();
props.setProperty("annotators", "tokenize, ssplit, pos, lemma, ner, parse, dcoref");
props.setProperty("sutime.binders", "0");

// We should change current directory, so StanfordCoreNLP could find all the model files automatically
var curDir = Environment.CurrentDirectory;
System.IO.Directory.SetCurrentDirectory(jarRoot);
var pipeline = new StanfordCoreNLP(props);
System.IO.Directory.SetCurrentDirectory(curDir);

// Annotation
var annotation = new Annotation(text);
pipeline.annotate(annotation);

// Result – Pretty Print
using (var stream = new ByteArrayOutputStream())
{
pipeline.prettyPrint(annotation, new PrintWriter(stream));
Console.WriteLine(stream.toString());
stream.close();
}
}
}
}

NOTE: After more exploring, I only get the above error when using the 3.5.1. If I use the corenlp linked to in the original article (stanford-corenlp-full-2014-10-31), it works fine.

@volhav Could you please test it on your machine? Thanks.

@bulltorious @sergey-tihon I've checked, as mentioned before, everything works fine with supported v3.5.0. I think the issue will be fixed when Sergey updates a package with a new version of Stanford.CoreNLP

[sergey-tihon]

@bulltorious Please try latest version from NuGet

[mike-a-ellis]

It is working now with the latest corenlp version. Thanks Sergey.

Hi Sergey,

I just ran into this exact same issue with the 3.5.2 package. Am I the only one?

It was working fine before I did a NuGet to go from 3.5.1 to 3.5.2.

Thanks,
Gimp

[sergey-tihon]

Please try this solution #19 (comment)

[gimp-dad]

Thanks, Sergey. Replacing code like

props.setProperty("sutime.binders", "0");

with

props.setProperty("ner.useSUTime", "0");

has fixed the issue.

Hey @sergey-tihon, any chance that your F# and C# samples could be updated to reflect this new requirement?

Thanks for your consideration. :)

Hi. Just got this error on a freshly-downloaded corenlp command line utility (2018-02-27) on Ubuntu 17.10. Is there a way to fix a command-line utility without compiling from source with the patch mentioned? Thank you.

UPDATE: sorry, I see this is a repo for a .NET, not the Standford.NLP itself
