A look back at OpenNLP's 2017.

Summary

OpenNLP got off to a quick start in 2017 thanks to a 1.7.0 release on December 31, 2016. This version added support for Java 8 and set the tone for OpenNLP's 2017. In total, there were 7 releases in 2017. OpenNLP also got a new logo and website in 2017 with an updated look and easier navigation. OpenNLP also released its first model, a language detection model capable of identifying 103 languages.

  • A new language model CLI tool.
  • Moses format support.
  • CONLL-U format support.
