"Abandoned before it's prime"

What do you like best?

OpenNLP has a nice and easy to understand API. The library is usable as a stand alone command line tool but can also be used within products which makes it easy to test new ideas on the CLI and the transition to productionizing a prototype is quick.

What do you dislike?

The project has been abandoned and is no longer up to date. There's also no indication in any parts of the API as to which functions and classes are thread safe versus not. I wish there was more example code in the documentation, and the models that have been trained that are available for download are from very long ago.

Recommendations to others considering the product

The documentation is lack luster. You will be doing a lot of your own digging.

What business problems are you solving with the product? What benefits have you realized?

Consistent tokenization and named entity recognition have been useful.
