Objectives and Topics:

The first Trust, Reputation and User Modeling (TRUM) workshop pursues

the following specific objectives:

o To bring researchers together from the communities of trust and

reputation modeling and user modeling;

o To initiate and facilitate discussions on the new trends in trust,

reputation and user modeling, and to move the trends forward.

o To provide a forum for cutting-age research

There are three ways in which the area of user modeling and the area

of trust and reputation modeling overlap.

First, decentralized and ubiquitous user modeling has sought inspiration

from research in multi-agent systems over the last 6 years, resulting

in a series of workshops at the UM conference in 2005, 2007 and UMAP 2009.

The current trend towards software apps using the cloud to store and

process information that can be downloaded on social networks and mobile

devices platforms brings new importance to the area of decentralized user

modeling. Frameworks for dynamic and purpose based sharing of user model

fragments among apps needs to take into account the trust among these

apps. The trust of one agent in another can be viewed as a simple user/agent

model. Researchers in the area of trust and reputation mechanisms have

studied for many years techniques allowing autonomous agents and peers

to share, aggregate and make decisions based on these simple user models.

User modeling researchers can gain useful insights from this area.

Second, the area of trust and reputation modeling has experienced rapid

growth in the past 7 years. Recently, two important trends have been

emerging in this area. One is the computational modeling of agents' cognition,

such as subjectivity and disposition, to achieve more accurate trust and

reputation modeling. Another trend is modeling of agents' trust using a

stereotype approach to deal with the problem of lack of experience. Both of

these trends are closely related to studies in user modeling. The evidential

success of these new trends inspires and encourages researchers in the

trust community to make use of the rich literature in user modeling to

develop more comprehensive trust and reputation modeling approaches.

Finally, a third important way in which research in user modeling overlaps

with trust is the user’s trust in the adaptive / personalized application.

In effect it is a symmetrical area to that of user modeling: while user

modeling suggests that the system models the user, here the user models the

system. It relates to issues of user’s understanding of the application,

and of the privacy and integrity of the user model data, both of which are

actively studied in the user modeling community. Facilitating the user’s

understanding and trust in the system’s functioning and the way it manages

the user’s data is very important, since it determines the user’s acceptance

of the application’s recommendations or persuasion, the user’s satisfaction

with the application’s functionality, and ultimately, its success.

Topics to be covered in this Workshop include but are not limited to:

Trust and Reputation Modeling

- Subjectivity and Disposition in Trust and Reputation Modeling

- Cognitive and Computational Trust

- Stereotype-based Trust Modeling

- Trust in Social Networks

- Trust-based Recommender Systems

- Trust and Reputation Modeling in Mobile Networks

- Models and mechanisms for privacy

User Modeling

- Decentralized User Modeling approaches

- Purpose-based user modeling

- Sharing of User model fragments

- User modeling in mobile computing, e.g. smart phone apps, vehicles, cameras

- User Modeling in ambient and ubiquitous computing
