Como funciona o iRank Score
Transparência total sobre como pontuamos e comparamos filmes e séries.
O que é o iRank Score?
O iRank Score é um número entre 0 e 100 que representa a qualidade crítica geral de um título. Em vez de confiar em uma única fonte, agregamos quatro das mais conceituadas usando uma média ponderada.
| Source | Weight | Min. votes required | Scale |
|---|---|---|---|
| IMDb | ×3.0 | 1,000 | 0–10 |
| Rotten Tomatoes | ×2.0 | 20 reviews | 0–100 → 0–10 |
| Metacritic | ×1.5 | 7 reviews | 0–100 → 0–10 |
| TMDb | ×1.0 | 100 | 0–10 |
Formula
iRank = (IMDb×3.0 + RT×2.0 + Metacritic×1.5 + TMDb×1.0) ÷ 7.5
Only sources that meet the minimum vote threshold are included. If a source is unavailable, the remaining weights are re-normalised so the score stays on the 0–10 scale.
Como medimos a similaridade
A similaridade entre dois títulos é calculada usando similaridade cosseno sobre um vetor de tags ponderadas. Quanto mais alinhados dois vetores, maior a pontuação de correspondência (0–100%).
Primary and secondary genres (action, drama, sci-fi…). The strongest signal for content similarity.
Emotional register — dark, comedic, inspirational, tense. Captures feel beyond genre labels.
Narrative rhythm: slow-burn vs. fast-paced. Affects viewer experience independently of genre.
Storytelling form: linear, non-linear, anthology, episodic, heist-structure, etc.
Decade of setting, not of release. A 2010 film set in the 1940s matches other period pieces.
Core ideas explored: redemption, identity, survival, political corruption, coming-of-age…
Target demographic — children, teens, adults, families. Prevents mismatched recommendations.
Narrative point-of-view: ensemble cast, single protagonist, unreliable narrator, etc.
The final match score shown on each page is the cosine similarity of the two weighted vectors, expressed as a percentage. A score of 90%+ means the titles share almost identical content DNA across all eight dimensions.
