What do you like best about openNLP?

Was working on a basic question-answering system using basic NLP methods compared to the Neural Nets. OpenNLP made my process much simpler with its wide variety of functions that are easy to use and when in trouble there is always an easily accessible documentation which is well written to cover almost all the possible general errors. Review collected by and hosted on G2.com.

What do you dislike about openNLP?

The NER Tagger and POS tagger are very different when compared to the other packages like spaCy and NLTK, which sometimes makes it harder to compare the outputs over certain categories. Review collected by and hosted on G2.com.

What problems is openNLP solving and how is that benefiting you?

Mainly using it for my research and academic coursework and projects. Review collected by and hosted on G2.com.

What do you dislike about openNLP?

I would definitely go with Spacy as it is more production focused and some of the tools of OpenNLP are not the most advanced. However, it is not so deep as NLTK and its API is not my favorite. Review collected by and hosted on G2.com.
