profile

A user profile is a visual display of personal data associated with a specific user, or a customized desktop environment. A profile refers therefore to the explicit digital representation of a person's identity. A user profile can also be considered as the computer representation of a user model. A user model is a (data) structure that is used to capture certain characteristics about an individual user, and the process of obtaining the user profile is called user modeling or profiling.
A profile can be used to store the description of the characteristics of a person. This information can be exploited by systems taking into account the person's characteristics and preferences.
User profiles can be found on operating systems, computer programs, recommender systems, or dynamic websites (such as online social networking sites or bulletin boards).
