2nd Call for Papers

International Workshop on
Ubiquitous and Decentralized User Modeling

 (in conjunction with UM'07

Paper Submission Deadline:
February 7, 2007

June 26, 2007, Corfu, Greece

Everyday work and leisure activities are supported and
enhanced with many computerized systems recording partial
user experience. Information technologies such as web
services, World Wide Web protocols and standards and
mobile technologies are foundations for integrated
user services available through the web or in ubiquitous
environments such as smart houses, intelligent hospitals,
city services, and so on. Web applications providing
integrated services, such as open marketplaces,
eLearning, as well as small personal computerized
devices such as PDAs and smart phones that allow access
to such services become widely available and even
essential tools in many situations. The ongoing
penetration of computers into everyday life generates
so-called ubiquitous computing environments where
computational power and networking capabilities are
available (and used) everywhere. However, in order
to provide users with personalized services in these
new environments some form of user modelling capability
must be considered as an essential and integral aspect.

** Ubiquitous user modelling ** describes the ongoing
modelling of user behaviour within a variety of
systems that share their user models and the
exploitation of the models to achieve personalized
and context-adapted services. The shared user
models can either be used for collective or for
individual adaptation goals. In contrast to other
environments, in ubiquitous environments, the
dynamics are typically higher, the contextual factors
more diverse and the computing resources of the
agents / services and their connectivity more limited.

** Decentralized user modelling ** studies how to
combine fragmentary / episodic user data and make
the most sense of it in the specific context while
coping with limited processing resources. Unlike
the first generation of web-based systems, where t
he assembled service is accessed through one point
(usually a web portal), in recent ubiquitous
and service-oriented context specific environments,
(e.g. advertisement services or multi-player
on-line games for cell phones or mobile tourist guides)
there isn’t necessarily a central integration point.
Instead, the service is dynamically created or
composed by several providers that must therefore
coordinate and negotiate with one another in order
to select the most suitable adaptation for the user.
Systems that can share their user models have the ability
to improve the coverage of user preferences (like
combining movies preferences with books preferences
and theatre preferences for leisure profile), level of
detail and the reliability of the integrated user models.
Consequently the quality of adaptation that may
be achieved, across a range of usage scenarios, is
likely to increase. The development of semantic
web technologies and standards in agents and
web-services enable such sharing.


Currently, issues relating to ubiquitous and
decentralized user modelling are gaining more
and more attention from research groups representing
the user modelling community, the HCI community,
the multi-agent systems community, and the ubiquitous
computing community. Additional communities that
are active in this area include those concentrating
on web services, service-oriented architectures
and innovative information systems. Many of
these communities are moving away from a
technically focused approach and starting
to consider more user-centred approaches to
context awareness and adaptation is among
their central research problems. The goal of
this workshop is to bring together both academic
and industrial researchers from these communities
to discuss new and innovative approaches to ubiquitous
and decentralized user modelling, to enhance
the exchange of ideas and concepts, to determine
the veins along the research should proceed and
to go one step further towards achieving the
widespread adoption personalization in ubiquitous computing.


Ubiquitous user modelling implies new challenges of
scalability, scrutability, privacy and trust.
Furthermore, new issues of decentralization and integration
have to be addressed. Topics of interest include,
but are not limited to:
- Generic user modelling in mobile and ubiquitous computing
- Context aware ubiquitous user modelling (in mobile and
  distributed environments)
- Construction and acquisition of distributed user models
- Semantic web approaches for user modelling
  (i.e. user model ontologies)
- Privacy, security and trust in decentralized user modelling
- Personalized and adaptive applications and
  interfaces in decentralized and ubiquitous environments
- Case studies, user experience and evaluation of
  ubiquitous and decentralized UM approaches
- Distributed architectures and interoperability
  of personalized applications like recommender systems,
  adaptive hypermedia, e-learning, adaptive navigation
  guides, personalized shopping guides, etc.
- Service-oriented architectures for decentralized
  and ubiquitous user modelling and adaptive systems
- Dynamic changes and their implications on the
  adaptive services in decentralized and ubiquitous environments
- Knowledge modelling, integration and management
  for personalization in constrained environments
- Reasoning methods in constrained environments
- Personalized content authoring, delivery and
  access in mobile environments
- Personalized multimedia applications
- Ubiquitous access to personalized applications
- Challenges for user personalization in
  mobile/distributed environments
