Re: Tesseract language

2018-10-21 Thread Alexandre Rafalovitch

There is a couple of things mixed in here:
1) Extract handler is not recommended for production usage. It is great for
a quick test, just like you did it, but going to production, running it
externally is better. Tika - especially with large files can use up a lot
of memory and trip up the Solr instance it is running within.
2) If you are still just testing, you can configure Tika within Solr but
specifying parseContent.config file as shown at the link and described
further down in the same document:
https://lucene.apache.org/solr/guide/7_5/uploading-data-with-solr-cell-using-apache-tika.html#configuring-the-solr-extractingrequesthandler
You still need to check with Tika documentation with Tesseract can take its
configuration from the parseContext file.
3) If you are still testing with multiple files, Data Import Handler can
iterate through files and then - as a nested entity - feed it to Tika
processor for further extraction. I think one of the examples shows that.
However, I am not sure you can pass parseContext that way and DIH is also
not recommended for production.

I hope this helps,
Alex.

2018-10-21 Thread Alexandre Rafalovitch

Usually, we just say to do a custom solution using SolrJ client to
connect. This gives you maximum flexibility and allows to integrate
Tika either inside your code or as a server. Latest Tika actually has
some off-thread handling I believe, to make it safer to embed.

For DIH alternatives, if you want configuration over custom code, you
could look at something like Apache NiFI. It can push data into Solr.
Obviously it is a bigger solution, but it is correspondingly more
robust too.

   Alex.

Re: Tesseract language

2018-10-21 Thread Gus Heck

Hi Martin,

I wrote a framework (https://github.com/nsoft/jesterj) that is meant to
help with small to medium custom solutions It's not (yet) ready for cases
where you need multiple machines feeding data, but so long as a single box
can do the work it should be useful. It has a basic Tika stage which is
ripe for enhancement. The example in the project uses Tika to extract text
from Shakespeare's plays, though I'll admit that the Tika processor class
it has not yet been given the full set of configuration options.  Fleshing
that out is on the list of things to do and would be easy and welcome as a
contribution (https://github.com/nsoft/jesterj/issues/74).

RE: Tesseract language

2018-10-26 Thread Martin Frank Hansen (MHQ)

Hi again,

Now I moved the OCR part to Tika, but I still can't make it work with Danish. 
It works when using default language settings and it seems like Tika is missing 
Danish dictionary.

My java code looks like this:

{
File file = new File(pathfilename);

Metadata meta = new Metadata();

InputStream stream = TikaInputStream.get(file);

Parser parser = new AutoDetectParser();
BodyContentHandler handler = new 
BodyContentHandler(Integer.MAX_VALUE);

TesseractOCRConfig config = new TesseractOCRConfig();
config.setLanguage("dan"); // code works if this phrase is 
commented out.

ParseContext parseContext = new ParseContext();

 parseContext.set(TesseractOCRConfig.class, config);

parser.parse(stream, handler, meta, parseContext);
System.out.println(handler.toString());
}

Hope that someone can help here.

Re: Tesseract language

2018-10-26 Thread Tim Allison

Tika relies on you to install tesseract and all the language libraries
you'll need.

If you can successfully call `tesseract testing/eurotext.png
testing/eurotext-dan -l dan`, Tika _should_ be able to specify "dan"
with your code above.

RE: Tesseract language

2018-10-26 Thread Martin Frank Hansen (MHQ)

Hi Tim,

You were right.

When I called `tesseract testing/eurotext.png testing/eurotext-dan -l dan`, I 
got an error message so I downloaded "dan.traineddata" and added it to the 
Tesseract-OCR/tessdata folder. Furthermore I added the 'TESSDATA_PREFIX' 
variable to the path-variables pointing to "Tesseract-OCR/tessdata".

Now Tesseract works with Danish language from the CMD, but now I can't make the 
code work in Java, not even with default settings (which I could before). Am I 
missing something or just mixing some things up?

Tika relies on you to install tesseract and all the language libraries you'll 
need.

If you can successfully call `tesseract testing/eurotext.png 
testing/eurotext-dan -l dan`, Tika _should_ be able to specify "dan"
with your code above.

Hi Martin,

Are you using it For image formats , I think you can try tess4j and use
give TESSDATA_PREFIX as the home for tessarct Configs.

I have tried it and it works pretty well in my local machine.

I have used java 8 and tesseact 3 for the same.

Hi Rohan,

Thanks for your reply, are you using tess4j with Tika or on its own?  I will 
take a look at tess4j if I can't make it work with Tika alone.

  Let’s move this over to user@tika.

Rohan,
  Is there something about Tika’s use of tesseract for image files that can
be improved?

RE: Tesseract language

2018-10-28 Thread Martin Frank Hansen (MHQ)

Hi Tim and Rohan,

Really appreciate your help, and I finally made it work (without tess4j).

It was the path-environment variable which had a wrong setting. Instead setting 
the path of TESSDATA_PREFIX to  'Tesseract-OCR/tessdata' I changed it to the 
parent folder 'Tesseract-OCR' and now it works for Danish.

Thanks again for helping.

Best regards

Martin

Martin,
  Let’s move this over to user@tika.

Rohan,
  Is there something about Tika’s use of tesseract for image files that can be 
improved?

Best,
   Tim
