c# issues

[tariqnahmad]

hi,

not really sure how to get this stuff working? ive downloaded various things (not sure what the difference is) :

1. CoreNLP from NuGet
2. http://sergey-tihon.github.io/Stanford.NLP.NET/StanfordCoreNLP.html
3. something else i forget

and now I have folders:

stanford-corenlp-full-2016-10-31 stanford-corenlp-full-2018-10-05 stanford-english-corenlp-2018-10-05-models

Q1: do i need to unzip ALL the jar files in these folders? I have unzipped some but it seems a bit hit and miss?

When I follow the c# code on this page http://sergey-tihon.github.io/Stanford.NLP.NET/StanfordCoreNLP.html I get an error on the line Dim pipeline = New StanfordCoreNLP(props):

edu.stanford.nlp.io.RuntimeIOException: 'Couldn't read TokensRegexNER from edu/stanford/nlp/models/kbp/english/gazetteers/regexner_caseless.tab'

IOException: Unable to open "edu/stanford/nlp/models/kbp/english/gazetteers/regexner_caseless.tab" as class path, filename or URL

Yes I know those files are missing - but why?

stanford-corenlp-full-2018-10-05 should work with latest NuGet.

the easiest way to ensure that you unzip it right is to check that isOk == true

Directory.SetCurrentDirectory(jarRoot);
var isOK = File.Exists(Path.Combine(Directory.GetCurrentDirectory(), "edu/stanford/nlp/models/kbp/english/gazetteers/regexner_caseless.tab"));
Debug.Assert(isOK);  
var pipeline = StanfordCoreNLP(props);

if it is false then your jarRoot path is incorrect

My stanford-corenlp-full-2018-10-05 folder contains 3 folders "patterns", "sutime" and "tokensregex". It also contains tons of .jar files and various other bits and bats.

No sign of a folder called "edu"?

[sergey-tihon]

It is inside jar with models, stanford-corenlp-3.9.2-models.jar. Rename this file to .zip and unzip.

[tariqnahmad]

OK, so you must be referring to stanford-corenlp-3.9.2-models.jar. Thats fine I'll try that.

But herein lies my issue, wheres the instructions telling us to do that? And do I need to unzip all the .jar files or just seemingly random ones?

In the getting started section on landing page and in FAQ section - https://sergey-tihon.github.io/Stanford.NLP.NET//faq.html#Stanford-NLP-CoreNLP-not-loading-models

it may be not clear, but Stanford NLP group distribute models differently with different tools
