I'm seeing good things about Python and NLTK. But back when I develop the core algo of TextTeaser (few months ago), I still don't know Python.

Right now, the TextTeaser website is coded using Python and Flask.

It shouldn't matter what language the OP decided to use, as long as it allows him/her to do whatever he/she set out to do in the first place.

Why use Python when Scala is a good alternative?

because NTLK is a very strong toolkit for natural language processing and i haven't found anything comparable in scala.

NLTK's strength is the clarity and flexibility of its code, for when you're experimenting with various processes and representations to find out what works.

If you have a single NLP model that already works, you wouldn't gain anything from rewriting it using NLTK. It would probably just get slower, because you're adding abstractions that you've already shown you don't need.

I say this as a fan of and (once) contributor to NLTK.

You can see from the source he's already using Apache OpenNLP. Scala is 100% interoperable with Java libs, so you have the entire Java ecosystem available, not just Scala code.

ya i saw that I'm not familiar with OpenNLP. lemme have a look it might solve my problem, I'm also starting a nlp project using scala :)

Why use Python instead of Scala?
