Come funziona il iRank Score

Piena trasparenza su come valutiamo e confrontiamo film e serie.

Cos'è l'iRank Score?

L'iRank Score è un numero tra 0 e 100 che rappresenta la qualità critica complessiva di un titolo. Invece di fidarci di una sola fonte, aggreghiamo quattro delle più autorevoli usando una media ponderata.

SourceWeightMin. votes requiredScale
IMDb×3.01,0000–10
Rotten Tomatoes×2.020 reviews0–100 → 0–10
Metacritic×1.57 reviews0–100 → 0–10
TMDb×1.01000–10

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.

Come misuriamo la similarità

La similarità tra due titoli viene calcolata usando la similarità coseno su un vettore di tag ponderati. Più due vettori sono allineati, più alto è il punteggio di corrispondenza (0–100%).

Genre50%

Primary and secondary genres (action, drama, sci-fi…). The strongest signal for content similarity.

Tone12%

Emotional register — dark, comedic, inspirational, tense. Captures feel beyond genre labels.

Pace10%

Narrative rhythm: slow-burn vs. fast-paced. Affects viewer experience independently of genre.

Structure8%

Storytelling form: linear, non-linear, anthology, episodic, heist-structure, etc.

Era7%

Decade of setting, not of release. A 2010 film set in the 1940s matches other period pieces.

Theme6%

Core ideas explored: redemption, identity, survival, political corruption, coming-of-age…

Audience4%

Target demographic — children, teens, adults, families. Prevents mismatched recommendations.

Perspective3%

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.
