Scrapping malaysianpaygap & Extracting data from the posts
Recently @malaysianpaygap has gotten quite famous as a platform that enables workers throughout Malaysia to anonymously share their salaries amongst other Malaysians. Its a great initiative and I am fully supportive behind ensuring that Malaysians are not taken advantage of by companies and get a liveable wage(especially when inflation is sky high).
NOTE: If you just want the data then you can download the zipped folder from here.
How to run
- Run the following to get conda environment setup
conda create --name pay python=3.7
conda activate pay
pip install -r requirements.txt
- Next we will need to scrape all the data from Instagram manually using BeautifulSoup! Just kidding I am too lazy so I will be using InstaLoader to do all the heavy lifting for me. The conda environment will have it installed for you already.
# you might need to pass in your username to login
instaloader --login=USERNAME profile malaysianpaygap --dirname-pattern={profile} --comments --no-profile-pic --post-metadata-txt="Caption: {caption}\n{likes} likes\n{comments} comments\n" --filename-pattern={date_utc:%Y}/{shortcode}
This should create the following directory structure:
|-- malaysianpaygap
| |-- 2022
| | |-- CaRp-1uPh8l.jpg # image
| | |-- CaRp-1uPh8l.json.xz
| | |-- CaRp-1uPh8l.txt # text data which was specified under --post-metadata-txt
| | |-- CaRp-1uPh8l_comments.json # all the comments
| | |-- CaT5MguPpDI.jpg
| | |-- CaT5MguPpDI.json.xz
| |-- 2022-02-27_04-58-58_UTC_profile_pic.jpg
| |-- id
| `-- malaysianpaygap_47523401972.json.xz
|-- requirements.txt
|-- scripts
| `-- entrypoint.sh
`-- src
|-- __init__.py
|-- extract_text_images.py
|-- main.py
|-- preprocess_comments.py
`-- preprocess_images.py
NOTE: Please do NOT change the directory structure, it will break the entire pipeline.
- You should have everything ready to run the preprocessing scripts that I have made! I have a bash script that runs everything in the correct order.
# make bash script runnable
chmod +x scripts/entrypoint.sh
bash scripts/entrypoint.sh
You should see the following output:

A new directory data will be created like so:
|-- data
| |-- comments.csv
| |-- comments.json
| |-- posts.csv
| |-- posts_text.csv
| `-- processed_images
| |-- CaRp-1uPh8l.jpg
| |-- CaT5MguPpDI.jpg
| |-- CaT6d2Yve5X.jpg
In the next section I will go over the data that was created.

FAQ
I am getting a ModuleNotFoundError: No module named 'src' error what can I do?
This is an issue with your PYTHONPATH, setting it to something like export PYTHONPATH="${PYTHONPATH}:/Users/yravindranath/REPO" should fix it.
Optimizations
- So currently the entire project isn't repoducible therefore I will dockerise it soon and allow anyone to run it locally without any issues.
- If you notice there is a slow
apply()used for binarizing the images and extracting the text from it using OCR. I am usingswifterto speed it up as it is.
