A study by nerds. Okay, seriously. Scripts for personality trait recognition based on structural metrics of tweets.

Full paper: "Analyzing Structural Metrics to Predict Twitter User Personality Traits".
Made with @zivhd & @kildor22. Part of Project Personality by @EdTheAlchemist.

Structural Metrics:

• Words per Tweet
• Characters per word
• Uppercase letters per Tweet
• Punctuation marks per Tweet
• Hashtags per Tweet
• Mentions per Tweet
• Links per Tweet
• Emojis per Tweet
• Emoticons per Tweet
• Consecutive repeated characters per word (ex. "hmmm")
• Consecutive repeated words per Tweet (ex. "pls pls pls")

Regression Models:

• Mean regression (baseline)
• Linear regression
• Support vector regression

Notes:

• Personality traits based on Five Factor Model
• Overwrite core.py from "emoji" library with the one in this repo
• Raw data available only to authors
