Trending Comments

Each comment is assigned a trending score that summarizes the replies and reactions it has received recently. Lists of comments can be ordered by their trending_score to show comments sorted by their trending score, see the ordering comments by trending docs for details.

Scoring calculation

The default trending score is calculate as (WR * R + WRe * Re) * e^(-λt) where the terms are:

• R = Number of direct replies
• WR = Weight of replies. Default = 2
• Re = Number of reactions
• WRe = Weight of reactions. Default = 1
• t = Time elapsed since the comment was posted, in minutes
• λ = Decay constant, controls how quickly older comments lose relevance. Default = 0.1
  • Higher λ, faster Decay (e.g. λ = 0.1)
  • Lower λ, slower Decay (e.g. λ = 0.01)

Customizing the scoring calculation

The weights (WR, WRe) and the decay constant (λ) can be customized for each client application, allowing flexibility to fine-tune how comment popularity and recency influence the trending score.
