Nowadays, many different applications in different areas (e-learning, digital libraries, search engines, online databases, e-commerce, social networks, ubiquitous computing, ...) are concentrating on collecting information about users for service personalization.

Because any specific network representation (in a specific application) uses different network models and different user modeling, aim of this workshop is to organize a common discussion among different scientific and industrial communities on evolving and secure multi-application personalization.

A first problem to address in this kind of scenario is to define accurately what the profile content is and how to represent users' properties and behaviors. Even for mono-application profiles there are several definitions and structure models, content categories and profile creation and enrichment methods. Are these techniques still valid in a multi-application context?

The profile management has to be user-centric. The user has to be an active actor and needs to be aware and to be able to control the stored information and its evolution. How to find and group similar profiles to enrich them mutually? Are similar profiles part of the same social community? How the profile modifications caused by an application affect the profile for another application? How to make the profile context-sensitive?

The user-centric character of the profile management means also that the actions of the user could affect the profile in an automatic manner. User tasks and action history model has to be taken into account in profile management.

Another difficulty with multi-application profiles is the security management due to profile data and structure sharing among different applications. Users must have the possibility to manage the confidentiality of their data in a direct and practical fashion. A credible solution must come with data security management taking into account user needs and application requirements. Which profile content can be shared, modified and used by several applications? What is useful, what is necessary and what is forbidden to be shared? How to guarantee users anonymity and privacy? How to prevent identity disclosure when profile content is shared among applications? Which trust and reputation techniques could be taken into account?
