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
