Want to learn how to use Python for Text Mining / Natural Language Processing (NLP)?
This repository has everything that you need to get started!
Author: Ties de Kok (Personal Page)
The goal of this GitHub page is to provide you with everything you need to get started with Python and Natural Language Processing (NLP)
The following topics are discussed:
(Note: the neural network part is only a reference to the Stanford course CS224n)
The topics and techniques demonstrated in this repository are primarily oriented towards empirical research projects in fields such as Accounting, Finance, Marketing, Political Science, and other Social Sciences.
However, many of the basics are also perfectly applicable if you are looking to use Python for any other type of Data Science!
This repository is written to facilitate learning by doing.
All the material is written up in a Jupyter Notebook. See:
The topics are split up by task description.
It is best to view the notebook locally or on nbviewer using this link: click here
environment.yml file is provided that you can install using
conda, this will automatically install all the packages used in the notebook.
Instructions on how to install the environment are provided here: Install environment
Please check out my "Getting started with Python for Research" repository: click here
To run the provided notebook file you need to use Jupyter Lab or Jupyter Notebook.
Jupyter comes pre-installed with the Anaconda distribution so you should have everything already installed and ready to go. The
environment.yml will also install Jupyter Lab if you prefer to use that.
What is the Jupyter Notebook?
From the Jupyter website:
The Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text.
In other words, the Jupyter Notebook allows you to program Python code straight from your browser!
How does the Jupyter Notebook work in the background?
The diagram below sums up the basics components of Jupyter:
At the heart there is the Jupyter Server that handles everything, the Jupyter Notebook which is accessed and used through your browser, and the kernel that executes the code. We will be focusing on the natively included Python Kernel but Jupyter is language agnostic so you can also use it with other languages/software such as 'R'.
It is worth noting that in most cases you will be running the
Jupyter Server on your own computer and will connect to it locally in your browser (i.e. you don't need to be connected to the internet). However, it is also possible to run the Jupyter Server on a different computer, for example a high performance computation server in the cloud, and connect to it over the internet.
How to start a Jupyter Notebook?
The primary method that I would recommend to start a Jupyter Notebook is to use the command line (terminal) directly:
conda activate PythonNLPTutorial
cd(i.e. Change) to the desired starting directory
This should automatically open up the corresponding Jupyter Notebook/Lab in your default browser.
You can also manually go to the Jupyter Notebook/Lab by going to
localhost:8888 with your browser.
How to close a Jupyter Notebook/Lab server?
If you want to close down the Jupyter Server: open up the command prompt window that runs the server and press
CTRL + C twice.
Make sure that you have saved any open Jupyter Notebooks!
How to use the Jupyter Notebook?
Some shortcuts are worth mentioning for reference purposes:
command mode --> enable by pressing
edit mode --> enable by pressing
You can essentially "download" the contents of this repository by cloning the repository.
You can do this by clicking "Clone or download" button and then "Download ZIP":
If you extract the downloaded ZIP to a folder you can start the Jupyter Notebook/Lab in that folder and access the notebook.
You can install the environment by following these steps:
cd(i.e. Change) to the folder where you extracted the ZIP file
conda env create -f environment.yml
conda activate PythonNLPTutorial
A full list of all the packages used is provided in the
Note: some functionality might not work on Binder.
