Researchers have developed personalized systems, which adapt their behavior to the goals, interests, and other characteristics of their users as individuals or members of particular groups.
Consider a typical information access system. Information is web resident. We distinguish four modules of this system: - one module is responsible for the selection of content that will be presented to the user
- one module is responsible for the presentation of the selected content to the user: what text, images will be presented, in what resolution, how the page will be organized etc
- another module offers different services to the user, e.g. searching, bookmarking, alert services etc
- a fourth module specifies the way the user interacts with the system, e.g. menus, buttons, shortcuts, etc
What distinguishes a personalized system from a traditional one is, first of all, the existence of profiles that store user information based on models of users as individuals or as members of groups.
These user models may be rather rudimentary or quite sophisticated.
User information is used by the system in order to adapt their behaviour to the needs, characteristics and preferences of users.
More specifically, to personalize the content, the presentation, services and interaction.
User profile information is inserted explicitly by the user or collected implicitly by the system by monitoring user interaction. This is the purpose of the User profiling module.

7. DM Technology Contributions
Traditional data management technologies has much
to offer that might be useful for general issues of
personalization/contextualization
Specialized indexing or stream mgmt for massive web-based recommendations
Heterogeneous profile integration
Several things are not in the hands
of AI, the semantic web, etc.
