DKpro StanfordNamedEntityRecognizer ClassCastException
Hi!
I tried to do the introductory example for DKpro. But DKpro's
StanfordNamedEntityRecognizer throws a ClassCastException. Any ideas?
I had to replace some code snippets with [...].
Thanks

AW: DKpro StanfordNamedEntityRecognizer ClassCastException
Posted by Ar...@bka.bund.de.
Hi Richard,
Nailed it. The pipeline with DKPro's StanfordNamedEntityRecognizer does work with uimafit-core:jar:2.0.0 and uimaj-core:jar:2.4.2 but it does not work with uimafit-core:jar:2.1.0 and uimaj-core:jar:2.6.0. It runs with uimafit-core:2.0.0 aund uimaj-core:2.6.0, too.
Thanks a lot,
Armin

Hi Armin,
I have absolutely no idea. I have rarely encountered this problem. Actually the only source of this that I remember is the use of the (de)serialization based on CASSerializer and/or CASCompleteSerializer (via CASImpl.reinit(...)).
Nothing related to this should have changed from uimaFIT 2.0.0 to 2.1.0. Does it work if you switch back to 2.0.0 (if you can)?
What kind of reader are you using?

Hi Richard!
It looks like your absolutely right. I have changed all JCas stuff in the consumer's resource to pure CAS and it works.
But why is JCas support not initialized? The reader calls an annotator for document meta data that uses JCas. It says "new DocumentMetaData(cas.getJCas())" and actually is annotated in the CAS.
All annotator's descriptions are build with AnalysisEngineFactory.createEngineDescription or read from an XML file. They are added to an AggregateBuilder. The aggregate description is given as second argument to SimplePipeline.runPipeline(). The first argument is the reader's descriptions. One of the ae's is the cas.getJCas() one you mentioned earlier.

Hi,
sounds like the JCas structures are not initialized. Maybe you also use the DKPro Core BinaryCasReader? If so, there was is a bug in DKPro Core 1.6.1 [1].
If you are initializing the CAS yourself or use the UIMA CAS serialization methods directly, then you should be able to fix this issue by calling this at some point before passing the CAS into your pipeline:
cas.getJCas()
As a quick fix, you could implement a simple analysis engine that does nothing else than calling cas.getJCas() in its process method and plug that in before the StanfordNamedEntityRecognizer.
Cheers,

Re: DKpro StanfordNamedEntityRecognizer ClassCastException
Posted by Richard Eckart de Castilho <re...@apache.org>.
Hi,
sounds like the JCas structures are not initialized. Maybe you also use the
DKPro Core BinaryCasReader? If so, there was is a bug in DKPro Core 1.6.1 [1].
If you are initializing the CAS yourself or use the UIMA CAS serialization
methods directly, then you should be able to fix this issue by calling this
at some point before passing the CAS into your pipeline:
cas.getJCas()
As a quick fix, you could implement a simple analysis engine that does
nothing else than calling cas.getJCas() in its process method and plug that
in before the StanfordNamedEntityRecognizer.
Cheers,
-- Richard
