Verifying Signatures

The md5, sha1, sha512, and asc files are signature files and can be used to verify the integrity of the downloaded distribution package.

Use the following commands to verify the integrity:

  • gpg --print-md MD5 fileName.zip

  • gpg --print-md SHA1 fileName.tar.gz

  • gpg --verify fileName.tar.gz.asc

It might be necessary to import the KEYS file to verify the integrity of the asc files.

That can easily be done with:

  • gpg --import KEYS

More information about release signing and verifying signatures can be found here.

SourceForge Models

The models on Sourceforge for 1.5.0 are found here and are fully compatible with Apache OpenNLP 1.9.3.

The models can be used for testing or getting started, please train your own models for all other use cases.
