Are there any equally great packages like Python's NTLK in Java world ?
Two popular ones that I know of are:
Gate
OpenNLP
Also LingPipe is really nice.
Stanford has a very good collection of NLP tools.
For other JVM languages see
- Scala: Scala NLP
- Clojure: clojure-opennlp
ClearTK provides a Java framework for doing statistical NLP. Its strength is not so much in its libraries, but in providing the infrastructure and wrappers for rich feature extraction and model training.
