How IMDb’s Rating System and Rankings Work – Score Calculation Methods, Types of Rankings, and Reliability Verification

When searching for information on movies and TV shows, many users rely on IMDb. Its rating system consists of scores based on reviews from users around the world, along with its own unique rankings. In particular, IMDb’s rankings allow users to quickly grasp the popularity and reputation of movies and dramas at a glance, making them a go-to reference for many people. Here, we’ll take an in-depth look at how IMDb scores are calculated, the types of rankings available, and how IMDb differs from other rating sites.

How IMDb Scores Are Calculated and Their Reliability – Review Aggregation Algorithms and Past Challenges

IMDb scores are calculated using a weighted average of user ratings out of 10 points. Rather than a simple average, the system adjusts the weighting of certain reviews and extreme scores to enhance reliability and prevent manipulation.

Key points to note include:

  • Not all user ratings are treated equally; more weight is given to reviews from active or long-term users.
  • Suspicious votes, such as those from bots or spam accounts, are excluded from the calculation to prevent manipulation.
  • Ratings from IMDbPro members or official affiliates are not reflected in the public score.

In the past, manipulation of ratings and fraudulent reviews were problematic, but improvements to the algorithm have since increased transparency and reliability.
