Rating Scale and Reputation System

Arumble Rating System Modeling aims to provide a platform for defining customized rating systems that remain interoperable with varying scales.


Rating systems vary by vendor and context.  Ratings also vary by creativity.  Some are extremely simple (and familiar), such as the infamous 5-star rating model.  Some systems are less mathematical and can be represented by letters, such as grates (A+, A, A-, B+, B, B-, etc).  There are others that use adjectives or other arbitrary words to describe the relevance of a rating in relation to a subject, such as “cold”, “warm”, “hot”, etc.  Sometimes arbitrary words are attributed to incremental models, such as the 5-star rating, to describe sentiment related to the weight given by a star rating.

All these styles (and many more) vary in scale and relevance.  Not all increments in rating are evenly distributed across the gamut of sentiment.  The challenge is to find a way to “normalize” varying rating scales so that they align similarly when compared to each other.  When this is achieved, it is possible to provide a platform for customizing ratings to your style and to the depth of detail you require.


The goal of a platform like this is not only to align many rating systems with each other, but to allow for expanding on existing scales and models to allow greater flexibility and user interaction.  There is a gap between the simplistic “rating” of a subject and the human expression of sentiment through words that form a “review”.

The Arumble Rating System aims to simplify the complexity of written reviews and to extend the flexibility of arbitrary ratings to express basic sentiment as both mediums converge in the middle.
