POS Model loading Issues
Hello!
I have been trying to use POS Models for POS tagging, but while loading the
Models I get the following exception:
java.io.EOFException: Unexpected end of ZLIB input stream
at java.util.zip.InflaterInputStream.fill(Unknown Source)
at java.util.zip.InflaterInputStream.read(Unknown Source)
at java.util.zip.ZipInputStream.read(Unknown Source)

I have tried loading the tokenizaton model (en-token.bin) and Its loading
and working fine.
Following is java source code that I am using to load Model:
InputStream is = new FileInputStream(MODEL_PATH);
POSModel model = new POSModel(is);
I have downloaded the models (en-pos-perceptron.bin,en-pos-maxent.bin) from
http://www.opennlp.org/models-1.5/. <http://www.opennlp.org/models-1.5/>

Hello,
the model file you are trying to load is damaged.
HTH,
