WAWC´2005
Conceptualization of User-Centric Personalization Management
Kari Heikkinen and Riku Suomela
Kari Heikkinen
Objectives
• to identify both user demand and user requirements for personalization management
• to apply personal information is both user centric personalization management and personalized service provisioning
• to build a conceptualization for personalization management to be implemented so that it supports user centricness
What is User Centricity?
• Trying to Understand the users ! • Beginning from finding out the real user
demand and user requirements• Ending to developing technology in a manner
it would serve the individual user in a best manner

Human Experience
People do not want to personalize ?
TRUE ! Majority of users use the default choices or change only little i.e. the layout of the web-page
Personalization may restrict the extent and the variety of information we receive
TRUE ! Indeed only getting certain kind of information could limit i.e. the decision-making and biased behaviour
People do not have well-defined preferences
TRUE ! In reality the choice of the user might be highly context or situation dependent and thus against any profile
People might be reluctant to give information about them
TRUE ! Privacy concerns are very high. On the other hand in some cases personal information is easily handed over.
Personalization is a black box solution to the users and the users do not usually know all details of the personalization and this could lead to the distrust of technology
TRUE ! The users wants to control own information and by doing so can trust the system more
Human Experience
What is Personalization Management?
• Personalization can be seen as a toolbox (or capability) that contains a set of technologies that enable the meeting of personal needs, requirements, preferences etc. of an individual user
• Personalization can be divided into explicit and implicit personalization
– implicit personalization is guided/managed solely by the personalization system (server)
– explicit personalization is user-defined and managed by the user (or system, or device)
What is Personalization Management?
• Personalization Management is often associated to an implicit system that guides, controls and maintains the whole personalization process
• In this thesis the notion ’personalization management’ is extended to explicit personalization in a manner the user can also guide, control and maintain the process

Conclusions
• An User-Centric Approach to Personalization Management and Service Provisioning– enables user-driven management of personal
information– applies both explicit and implicit personalization– integrates contextual and situation-dependant
information to personal information management and service provisioning
• Is a complete personalization scheme, built on user demand and on user requirements, taking account also the different parameters of network performance
• Provides a basis for faster adoption of personalization technologies and new services
