• CTR (Click-Through Rate):‍

(Clicks / Impressions) × 100

‍

• Follower Growth Rate:

• Sentiment Analysis
  Uses NLP to classify opinions as positive, neutral, or negative.
  Average sentiment:

 Sentiment Score = Σ sentiment(i) / n

  ‍

  Examples:
  ‍
  • Degree Centrality
    
  • Betweenness Centrality:
    

BC = Σ(σst(v) / σst)

‍

Mathematical Representation

• ‍Engagement Rate:

ER = (Σ interactions / impressions) × 100

‍

• Moving Average (Trend Tracking):
  

MA = (1 / t) × Σ engagement(i) over t

‍

• Topic Modeling:
  Often performed using Latent Dirichlet Allocation (LDA) to classify text into themes.
