## Installation
```python
! pip install johnsnowlabs
from johnsnowlabs import nlp
nlp.load('emotion').predict('Wow that was easy!')
```
See [the documentation](https://nlp.johnsnowlabs.com/docs/en/install) for more details.
## Usage
These are examples of getting things done with one line of code.
See the [General Concepts Documentation](https://nlp.johnsnowlabs.com/docs/en/concepts) for building custom pipelines.
```python
# Example of Named Entity Recognition
nlp.load('ner').predict("Dr. John Snow is an British physician born in 1813")
```
Returns :
| entities | entities_class | entities_confidence |
|-----------|----------------|:--------------------|
| John Snow | PERSON | 0.9746 |
| British | NORP | 0.9928 |
| 1813 | DATE | 0.5841 |
```python
# Example of Question Answering
nlp.load('answer_question').predict("What is the capital of Paris")
```
Returns :
| text | answer |
|-------------------------------|--------|
| What is the capital of France | Paris |
```python
# Example of Sentiment classification
nlp.load('sentiment').predict("Well this was easy!")
```
Returns :
| text | sentiment_class | sentiment_confidence |
|---------------------|-----------------|:---------------------|
| Well this was easy! | pos | 0.999901 |
```python
nlp.load('ner').viz('Bill goes to New York')
```
Returns:
For a full overview see the [1-liners Reference](https://nlp.johnsnowlabs.com/docs/en/examples) and [the Workshop](https://github.com/JohnSnowLabs/spark-nlp-workshop).
## Use Licensed Products
To use John Snow Labs' paid products like [Healthcare NLP](https://www.johnsnowlabs.com/healthcare-nlp), [Visual NLP], [Legal NLP], or [Finance NLP], get a license key and then call nlp.install() to use it:
```python
! pip install johnsnowlabs
# Install paid libraries via a browser login to connect to your account
from johnsnowlabs import nlp
nlp.install()
# Start a licensed session
nlp.start()
nlp.load('en.med_ner.oncology_wip').predict("Woman is on chemotherapy, carboplatin 300 mg/m2.")
```
## Usage
These are examples of getting things done with one line of code.
See the [General Concepts Documentation](https://nlp.johnsnowlabs.com/docs/en/concepts) for building custom pipelines.
```python
# visualize entity resolution ICD-10-CM codes
nlp.load('en.resolve.icd10cm.augmented')
.viz('Patient with history of prior tobacco use, nausea, nose bleeding and chronic renal insufficiency.')
```
returns:
```python
# Temporal Relationship Extraction&Visualization
nlp.load('relation.temporal_events')\
.viz('The patient developed cancer after a mercury poisoning in 1999 ')
```
returns:
