# NLU: The Power of Spark NLP, the Simplicity of Python
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, with **everything in 1 line of code.**



## NLU in Action 
See how easy it is to use any of the **thousands** of models in 1 line of code, there are hundreds of [tutorials](https://nlu.johnsnowlabs.com/docs/en/notebooks) and [simple examples](https://github.com/JohnSnowLabs/nlu/tree/master/examples) you can copy and paste into your projects to achieve State Of The Art easily.

## Getting Started with NLU 
To get your hands on the power of NLU, you just need to install it via pip and ensure Java 8 is installed and properly configured. Checkout [Quickstart for more infos](https://nlu.johnsnowlabs.com/docs/en/install)
```bash 
pip install nlu pyspark==3.0.2
``` 

## Loading and predicting with any model in 1 line python 
```python
import nlu 
nlu.load('sentiment').predict('I love NLU! <3') 
``` 

## Loading and predicting with multiple models in 1 line 

Get 6 different embeddings in 1 line and use them for downstream data science tasks! 

```python 
nlu.load('bert elmo albert xlnet glove use').predict('I love NLU! <3') 
``` 

## What kind of models does NLU provide? 
NLU provides everything a data scientist might want to wish for in one line of code!  
 - NLU provides everything a data scientist might want to wish for in one line of code!
 - 1000 + pre-trained models
 - 100+ of the latest NLP word embeddings ( BERT, ELMO, ALBERT, XLNET, GLOVE, BIOBERT, ELECTRA, COVIDBERT) and different variations of them

- Chunk Matcher
- Phrases Matcher
- Stopword Cleaners
- Pattern Cleaners
- Slang Cleaner 

## Where can I see all models available in NLU? 
For NLU models to load, see [the NLU Namespace](https://nlu.johnsnowlabs.com/docs/en/namespace) or the [John Snow Labs Modelshub](https://modelshub.johnsnowlabs.com/models)  or go [straight to the source](https://github.com/JohnSnowLabs/nlu/blob/master/nlu/namespace.py).

## Supported Data Types
- Pandas DataFrame and Series
- Spark DataFrames
- Modin with Ray backend
- Modin with Dask backend
- Numpy arrays
- Strings and lists of strings 

## Overview of all tutorials using the NLU-Library

In the following tabular, all available tutorials using NLU are listed. These tutorials will help you learn the 
usage of the NLU library and on how to use it for your own tasks. Some of the tasks NLU does are
translating from any language to the english language, lemmatizing, tokenizing, cleaning text from 
Symbol or unwanted syntax, spellchecking, detecting entities, analyzing sentiments and many more!
