Document Categorizer - Classifying: Help
Hi, everyone.
I'm trying to use Document Categorizer - Classifying, but I could not run
the example ...
I saw the documentation:
http://opennlp.apache.org/documentation/1.5.2-incubating/manual/opennlp.html#opennlp
Can anyone help me with this?
Thanks for all.

Yes, looks good. Format is class label + document in one line.
The document is whitespace tokenized.

In first time, I used this file:
GMDecrease Major acquisitions that have a lower gross margin than the
existing network also
GMIncrease The upward movement of gross margin resulted from amounts
pursuant to adjustments
Second, this:
GMDecrease Major acquisitions that have a lower gross margin than the
existing network also \
had a negative impact on the overall gross margin, but it
should improve following \
the implementation of its integration strategies .
GMIncrease The upward movement of gross margin resulted from amounts
pursuant to adjustments \
to obligations towards dealers .
as documentation sample.
where, GMDecrease and GMIncrease are class. Ok?
I saw that I must use more document in training, correct? So, how can I
represent many document in one class? This way:
GMDecrease Major acquisitions that have a lower gross margin than the
existing network also
GMDecrease To perform classification you will need a maxent model - these
are encapsulated in the DoccatModel class of OpenNLP tool
GMDecrease First you need to grab the bytes from the serialized model on an
InputStream - we'll leave it you to do that, since you were the one who
serialized it to begin with. Now for the easy part
GMDecrease The Document Categorizer can be trained on annotated training
material. The data must be in OpenNLP Document Categorizer training format.
...
GMIncrease The upward movement of gross margin resulted from amounts
pursuant to adjustments
GMIncrease The tags array contains one part-of-speech tag for each token in
the input array

Anyway, the output indicates

Looks like the mailing list sever removed your attachment. Anyway, the
output indicates
that you just used two training documents. Was this intended?
Otherwise there might be an issue with the format.

Ok...
I was trying use the documentation sample, 'cause I need to know if I can
use OpenNLP in my master's thesis as an experiment.
I attached the file that I used. I need to know if the format, that I used,
is correct.

Sorry for this bug. We have a jira for it, but no one every took time to
fix it.
Well, instead of the stack trace you should see an error message which
tells you that you don't have enough training data.
You should try with a few hundred examples at least, otherwise
the model you produce will not really work.

Looks like you do not have the maxent jar on the classpath.
Maybe it is just an issue with our script (does that work with head?).
Anyway, try to go to this dir:
C:\Program Files\Apache Software Foundation\opennlp-tools-1.5.0
and type: bin/opennlp
Or does it not work because of the whitespace in Program Files?
I suggest that you try 1.5.2, if I remember it correctly we spent some

Hi, Adriano,
We don't have any ready to use model for Document Categorizer yet. You
should try training your own using the instructions.

To perform classification I need a maxent model. But I don’t have an
example this. In the others tasks (Name Finder, Tokenizer, Sentence
Detector...) has example... I’m beginner in the OpenNLP and I’d like run
all existents examples.
Can you help me?
