[jira] [Commented] (OPENNLP-428) make EOS character set configurable

["Katrin Tomanek (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENNLP-428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204540#comment-13204540 ] 

Katrin Tomanek commented on OPENNLP-428:
----------------------------------------

Short explanation to my patch: the sentence detector logic now has a new parameter, which can be specified for the CMD-Line tools (eosChar). Here, you can specify characters to be used as EOS symbols. eosChars is optinal; if not specified, the default EOS symbols (as defined in the Factory, language-dependent) are used. 

Note: specifying eosChars will override the logic caused by language in the Factory class.

I also modified the cross-validator, the evaluator, the trainier etc to use the EOS symbols.

EOS symbols, if provided, are stored in the models manifest.

> Currently, the EOS symbols to be used by the sentence detector cannot be configured (at the moment, a user would have to make changes in opennlp.tools.sentdetect.lang.Factory
> Since it is important to use the same EOS symbols during training and during testing/prediction, the EOS symbols should be stored with the model's properties
