Trend intelligence
Trending is not “most articles”. A story trends when several signals move together. The score is a weighted geometric mean of eight factors — all shown on every card, none hidden.
| Factor | Weight | What it measures |
|---|---|---|
| Recency | 0.14 | time since the last meaningful update |
| Velocity | 0.16 | acceleration of independent-family publication |
| Source diversity | 0.12 | how many independent newsrooms |
| Geographic relevance | 0.14 | Tamil Nadu > India > abroad-relevant |
| Category weight | 0.12 | crisis > politics > finance > sports |
| Consequence | 0.16 | official alert, wide district impact, corroboration |
| Novelty | 0.08 | a new fact or correction beats a repeat |
| Corroboration | 0.08 | independent confirmation or an official primary source |
Full model and a worked example: docs/TREND-MODEL.md. A geographic-relevance of zero (an out-of-scope story) removes the item entirely.
Cleared the trend bar and has at least two independent source families (or an official primary source).
