# Available as a Book: [NLP in Python - Quickstart Guide](https://www.amazon.in/dp/B07L3PLQS1)



### Written for Practicing Engineers



This work builds on the outstanding work which exists on Natural Language Processing. These range from classics like Jurafsky's Speech and Language Processing to rather modern work in The Deep Learning Book by Ian Goodfellow et al.



While they are great as introductory textbooks for college students - this is intended for practitioners to quickly read, skim, select what is useful and then proceed. There are several notebooks divided into 7 logical themes.



Each section builds on ideas and code from previous notebooks, but you can fill in the gaps mentally and jump directly to what interests you.



## Chapter 01 

[Introduction To Text Processing, with Text Classification](https://github.com/NirantK/nlp-python-deep-learning/blob/master/Part-01.ipynb)

- Perfect for Getting Started! We learn better with code-first approaches



## Chapter 02

- [Text Cleaning](https://github.com/NirantK/nlp-python-deep-learning/blob/master/02-A.ipynb) notebook, code-first approaches with supporting explanation. Covers some simple ideas like:

  - Stop words removal

  - Lemmatization

- [Spell Correction](https://github.com/NirantK/nlp-python-deep-learning/blob/master/02-B.ipynb) covers **almost everything** that you will ever need to get started with spell correction, similar words problems and so on



## Chapter 03

[Leveraging Linguistics](https://github.com/NirantK/nlp-python-deep-learning/blob/master/Part-03%20NLP%20with%20spaCy%20and%20Textacy.ipynb) is an important toolkit in any practitioners toolkit. Using **spaCy** and textacy we look at two interesting challenges and how to tackle them: 

- Redacting names 

  - Named Entity Recognition

- Question and Answer Generation

  - Part of Speech Tagging

  - Dependency Parsing



## Chapter 04

[Text Representations](https://github.com/NirantK/nlp-python-deep-learning/blob/master/Part-04%20Text%20Representations.ipynb) is about converting text to numerical representations aka vectors

- Covers popular celebrities: word2vec, fasttext and doc2vec - document similarity using the same

- Programmer's Guide to **gensim**



## Chapter 05

[Modern Methods for Text Classification](https://github.com/NirantK/nlp-python-deep-learning/blob/master/Part-05%20Modern%20Text%20Classification.ipynb) is simple, exploratory and talks about:

- Simple Classifiers and How to Optimize Them from **scikit-learn**

- How to combine and **ensemble** them for increased performance

- Builds intuition for ensembling - so that you can write your own ensembling techniques



## Chapter 06

[Deep Learning for NLP](https://github.com/NirantK/nlp-python-deep-learning/blob/master/Part-06%20Deep%20Learning%20for%20NLP.ipynb) is less about fancy data modeling, and more engineering for Deep Learning

- From scratch code tutorial with Text Classification as an example

- Using **PyTorch** and *torchtext*

- Write our own data loaders, pre-processing, training loop and other utilities



## Chapter 07

[Building your own Chatbot](https://github.com/NirantK/nlp-python-deep-learning/blob/master/Part-07%20Building%20your%20own%20Chatbot%20in%2030%20minutes.ipynb) from scratch in 30 minutes. We use this to explore unsupervised learning and put together several of the ideas we have already seen. 

- simpler, direct problem formulation instead of complicated chatbot tutorials commonly seen

- intents, responses and templates in chat bot parlance

- hacking word based similarity engine to work with little to no training samples
