Slide 4 - Methodology

The Methodology workflow slide outlines four phases for tweet sentiment analysis: Data Collection via Twitter API, Preprocessing with Python (NLTK, pandas), Sentiment Scoring using VADER, and Visualization Pipeline with Matplotlib and Seaborn. It describes gathering tweets, cleaning text and removing stopwords, computing compound sentiment scores, and generating histograms, word clouds, and similar visuals.

Slide 6 - Structural Neutrality Insights

Neutral tweets consistently achieve higher retweet counts than biased ones, preserving structural virality. Positive and negative tweets show engagement biases, but neutrality maintains network integrity.

Structural Neutrality Insights

Neutral Tweets: Higher RetweetsPos/Neg Bias in Virality
Neutral sentiment tweets consistently achieve higher retweet counts compared to biased ones, indicating structural preservation in virality.Positive and negative tweets show engagement biases. Key insight: Neutrality maintains network integrity. [Icon: Balance Scale]

Slide 7 - Multivariate Analysis

The Multivariate Analysis slide reveals a moderate positive Likes-Sentiment correlation of 0.65 and a Retweets-Sentiment correlation of 0.58, consistent with the likes trend. It examines 5 key dimensions via a parallel coordinates plot.

Multivariate Analysis

  • 0.65: Likes-Sentiment Correlation
  • Moderate positive relationship

  • 0.58: Retweets-Sentiment Correlation
  • Consistent with likes trend

  • 5: Key Dimensions Analyzed
  • Via parallel coordinates plot

Speaker Notes
