Basis for future vision ๏ Personalisation is the key for differentiation / individuality
– based on: • Context (social context, terminal and network capabillities, location etc.)• Personal preferences and data (which may vary depending on context)
– used for: • Filtering of content • Customisation of information presented• Service discovery• Tagging of data
๏ Personalisation components– Rendering– Personal assistants– Context sensors– User profile– Secure and seamless authentication
๏ Users involvement– Have roles (e.g. fisherman,..) according to context and personal preferences– Personal assistant (Avatar) which takes over certain tasks
Presented in Jan 2003
8.1.2003, Josef Noll Personalisation 5
Reasons supporting the Vision
๏ Ongoing trends– Individualism– Industry turns to be service provider– Specialisation and information overload– Communication capabilities and processors in each device– Network diversity (speed, price…)
๏ Need– Filtering of information, forced by Moore’s law, 3x info/12 months– Adjust to individual roles and situations– Information and services adjusted to user needs
๏ How– Extended user profile and context are basis for individual adjustements, e.g.
don’t interrupt from work when fishing๏ Why
– Happy and loyal customers, e.g. trust of secure information handling, services that fulfil specific user needs
8.1.2003, Josef Noll Personalisation 6
Personalised Profile & Context๏ The preferences and settings of a user are captured in the
user profile. ๏ For each user there will be allocated one unique user profile๏ The user should be able to access to multiple applications
and services anytime, anywhere and on any terminal in the same way he/she is used to independent of device or location

Requirements on the User Profile๏ Expandable user profile to incorporate additional
preferences and settings, e.g. start gymnastics๏ For each application the user profile must contain the
information necessary for the presentation of the application on the terminal types requested by the user.
๏ For each application the user profile must contain application restrictions which specifies the usage restrictions.
๏ User profile incorporates personal data such as address book, telephone list, bookmarks, calendar appointments, personal interests or preferences etc.

The overall user experience
๏ Usability is extremely important. Ease of use, system stability and speed are crucial factors.
๏ Complicated procedures associated with set up of systems inhibits use.
๏ Infrastructure and system resources will vary in an ad hoc (wireless) network, this then is part of a users context and is critical to functionality and overall user experience.
๏ Technology must not hamper or complicate personalisation features/use from a user standpoint. Development must occur in relation to users terms and not defined completely by technology.

User profiles/profiling -The comments “Now” - 2008

Visions take time to get realised Technology is in place, Services are coming Mobile phones are becoming the source for Internet and Service access20-30 % of all phones worldwide will be smartphones by
200930 % of mobile users in the Nordic will receive push
content by 2010 Market need for personalisation: “Mobile advertisement has to fit to the user, otherwise it will fail completely”

Resource Description Framework (RDF)
W3C recommendation (http://www.w3.org/RDF) RDF is graphical formalism ( + XML syntax + semantics)
for representing metadata for describing the semantics of information in a machine- accessible way
RDF is a basic ontology language Resources are described in terms of properties and property values using RDF
statements. Statements are represented as triples, consisting of a subject, predicate and
object. [S, P, O]
