A Model of Reputation

3,547

Published on

A simple model for reputation is presented: reputation is information used to make value judgments about a person or thing within a context for a time.

Each of the concepts are discussed in some detail, and finally a simple example is presented (traffic estimates on Google Maps for Android) that demonstrates the model at work, and how to use it to make system design improvements.
