John Snow Labs' NLU is a Python library for applying state-of-the-art text mining, directly on any dataframe, with a single line of code. As a facade of the award-winning Spark NLP library, it comes with 1000+ of pretrained models in 100+ , all production-grade, scalable, and trainable and everything in 1 line of code.

See how easy it is to use any of the thousands of models in 1 line of code, there are hundreds of tutorials and simple examples you can copy and paste into your projects to achieve State Of The Art easily.

This 1 line let's you visualize and play with 1000+ SOTA NLU & NLP models in 200 languages for Named Entitiy Recognition, Dependency Trees & Parts of Speech, Classification for 100+ problems, Text Summarization & Question Answering using T5 , Translation with Marian, Text Similarity Matrix using BERT, ALBERT, ELMO, XLNET, ELECTRA with other of the 100+ wordembeddings and much more using Streamlit .
