Getting Started

Prerequisites

• Python3 (3.9.5)
  • See the official webpage for download information.
• Conda
  • You are welcome to use other package management systems, but I ran into a lot of trouble with pip on a Mac M1. I installed conda through Miniforge.

Installation

1. git clone https://github.com/hein-j/reddit-sentiment-analysis.git
2. cd into project root
3. Install dependencies (into a virtual environment if you wish)
   1. For conda: conda create --prefix ./venv --file requirements.txt and then conda activate ./venv
   2. If you run into trouble or are not using conda, the dependencies are:
      1. praw
      2. nltk
      3. pandas
      4. emoji
      5. spacy
      6. plotly
4. Download 'wordnet' and 'vader_lexicon' from nltk (See instructions here)
5. Download spacy model: python -m spacy download en_core_web_sm
6. Create a reddit app (See here for help)
7. Create a praw.ini file in project root. Name the site bot. Include client_id, client_secret, and user_agent. (See here for help)
8. You should now be good to go 🤘
