State of the art on mechanisms for personalization of information

Abstract

With the exponential growth in the volume of data and the heterogeneity of information, users are facing increasing difficulties in identifying relevant information, irrelevant information, or even noise. To overcome these issues, mechanisms for customizing information have emerged. The personalization of information consists in adapting the information according to the preferences and/or access context of the user. Context can be seen as any information that describes an entity. The user's preferences are combined in a profile. The user profile can be seen as a setting in factor of the invariant part of the user's preferences. The mechanisms for personalizing information are mainly based on the user profile and the user's access context. The personalization of information cannot be seen as a domain in itself because it is used in various technological fields, namely: the field of information retrieval, the field of databases and the field of human-machine interfaces. The objective of this work is to provide an overview of the mechanisms of information personalization by presenting their foundations and showing you how information personalization is used in the various technological areas mentioned above.
